Good day.

Most home computers (and laptops) come with speakers or headphones (sometimes both) connected. Quite often, in addition to the main sound, the speakers begin to play all sorts of extraneous sounds: mouse scrolling noise (a very common problem), various crackling sounds, trembling, and sometimes a slight whistle.

In general, this question is quite multifaceted - there can be dozens of reasons for the appearance of extraneous noise... In this article I want to point out only the most common reasons why extraneous sounds appear in headphones (and speakers).

Reason #1 - problem with the connection cable

One of the most common reasons for the appearance of extraneous noise and sounds is poor contact between the computer's sound card and the sound source (speakers, headphones, etc.). Most often, this happens due to:

• damaged (broken) cable that connects the speakers to the computer (see Fig. 1). By the way, in this case you can also often observe the following problem: there is sound in one speaker (or headphone), but not in the other. It is also worth noting that a broken cable is not always visible to the eye; sometimes you need to install headphones to another device and test it to get to the bottom of the truth;
• poor contact between socket network card PC and headphone plug. By the way, very often it helps to simply remove and insert the plug from the socket or turn it clockwise (counterclockwise) to a certain angle;
• loose cable. When it starts to hang out from a draft, pets, etc., extraneous sounds begin to appear. In this case, the wire can be attached to the table (for example) with regular tape.

By the way, I also observed the following picture: if the cable for connecting the speakers is too long, extraneous noise may appear (usually subtle, but still annoying). When the length of the wire was reduced, the noise disappeared. If your speakers are very close to your PC, it might be worth trying to change the length of the cord (especially if you use some extension cords...).

In any case, before you start looking for problems, make sure that everything is in order with the hardware (speakers, cable, plug, etc.). To check them, just use another PC (laptop, TV, etc.).

Reason #2 - driver problem

Anything can happen due to driver problems! Most often, if the drivers are not installed, you will have no sound at all. But sometimes, when the wrong drivers were installed, it may not be observed at all correct work device (sound card) and therefore various noises appear.

Problems of this nature also often appear after reinstallation or Windows updates. By the way, Windows itself very often reports that there are problems with drivers...

To check if everything is ok with the drivers, you need to open device Manager (Control Panel\Hardware and Sound\Device Manager- see fig. 2).

In Device Manager you need to open the " Audio inputs and outputs"(see Fig. 3). If yellow and red exclamation marks are not displayed in this tab next to the devices, it means that there are no conflicts or serious problems with the drivers.

Reason #3 - sound settings

Quite often, one or two ticks in the sound settings can completely change the clarity and quality of the sound. Quite often, noise in the sound can be observed due to the inclusion of PC Beer and the line input (and other things, depending on the configuration of your PC).

To configure the sound, go to Control Panel\Hardware and Sound and open the tab " Volume settings"(as in Fig. 4).

In the “Levels” tab there should be the treasured “PC Beer”, “CD”, “Line input”, etc. (see Fig. 6). Reduce the signal level (volume) of these devices to a minimum, then save the settings and check the sound quality. Sometimes after these settings are entered, the sound changes dramatically!

Reason #4: Speaker volume and quality

Often, hissing and crackling in speakers and headphones appears when their volume reaches maximum (on some, noise appears when the volume rises above 50%).

This happens especially often with inexpensive speaker models; many people call this effect “jitter.” Please note: this may be the reason - The volume on the speakers is turned up almost to maximum, and in Windows itself is turned down to minimum. In this case, simply adjust the volume.

In general, it is almost impossible to get rid of the “jitter” effect at high volumes (of course, without replacing the speakers with more powerful ones)…

Reason #5: Power supply

Sometimes the reason why noise appears in headphones is power supply diagram(this recommendation is for laptop users)!

The fact is that if the power supply circuit is set to power saving (or balance) mode, perhaps the sound card simply does not have enough power - this is why extraneous noise is observed.

The solution is simple: go to Control Panel\System and Security\Power Options- and select the mode “ High performance"(this mode is usually hidden in the additional tab, see Fig. 7). After this, you also need to connect the laptop to the power supply, and then check the sound.

Reason #6: Grounding

The point here is that the computer case (and often the speakers too) passes electrical signals through itself. For this reason, various extraneous sounds may appear in the speakers.

To exclude this problem- one simple trick often helps: connect the computer case and the battery with a regular cable (cord). Fortunately, there is a heating radiator in almost every room where a computer is located. If the reason was grounding, this method in most cases eliminates interference.

Mouse noise when scrolling the page

Among the types of noise, the prevailing extraneous sound is the sound of a mouse when it scrolls. Sometimes it is so annoying that many users have to work without sound at all (until the problem is fixed)…

Such noise can occur for various reasons; it is not always easy to establish. But there are a number of solutions to try:

1. replacing the mouse with a new one;
2. replacing a USB mouse with a PS/2 mouse (by the way, many PS/2 mice have a mouse connected via an adapter to USB - just remove the adapter and connect directly to the PS/2 connector. Often the problem disappears in this case);
3. replacing a wired mouse with a wireless one (and vice versa);
4. try connecting the mouse to a different USB port;
5. installing an external sound card.

Rice. 8. PS/2 and USB

PS

In addition to all of the above, speakers may begin to produce noise in the following cases:

• before the call mobile phone(especially if he lies close to them);
• if the speakers are too close to the printer, monitor, or other equipment.

That's all I have on this issue. I would be grateful for constructive additions. Good job 🙂

This can happen to anyone when, when you turn on the computer, instead of the usual melody, you hear only noise system unit. No sound on the computer! Why did the sound disappear, what should I do? All that remains is in the silence and silence of the speakers, go to the Internet and ask the question: “Why is there no sound on the computer?” Here we discuss the most common reasons for the lack of sound on the computer and ways to eliminate them.

The reason for the lack of sound on a computer can only be in the software or hardware environment (). That is, it turns out that you have problems with the system settings or programs, or that the computer components (speakers, sound card) are faulty. This does not directly depend on the operating system installed on the computer. This can happen with Windows XP, Linux, and even new operating systems. Windows systems 7 and Windows 8. Even if the speakers with headphones and the installed sound card are the most modern and expensive.

How to restore sound?

First you need to find out the reason for the lack of sound. You can find out in different ways, but first you need to try the simplest thing.
So, step-by-step recovery sound. Each step you take will bring you closer to the desired result.

1). Try restarting the computer; there is a possibility that the sound will appear at startup after restarting the operating system. This happens when drivers for a sound card are updated.

2). Check that the speaker plug is inserted well into the power outlet, if at all. Check whether the speakers themselves are connected to the computer and whether the plug is inserted well. If you find these problems, correct them.

3). Check the switch on the speakers, it may be in the “off” position. Turn on the speakers, turn the volume control to increase. If everything is in order, then the LED on the column where the regulator knob is installed (present on almost all models) should light up.

The speakers must be turned on - the power light on one of them must be on.

4). On the taskbar, find the speaker icon. It should not be crossed out. If it is turned off, then you just need to turn on the sound by clicking on the “Turn on sound” button.

If the desktop icon appears as disabled. You need to click on the speaker logo.

5). There, on the taskbar, check the set speaker level; it may well be that it is reduced to a minimum or to zero. If so, increase the volume by raising the slider to the desired level.

6). It is worth checking the speakers for performance using any other sound source. On your phone, player or other computer.

7). Look in Device Manager for missing unknown devices. Such devices are indicated by an exclamation mark.

Open “Device Manager” like this: Start -> Control Panel -> System and Security. In the "System" section, find the inscription "Device Manager". All devices displayed there must be recognized, i.e. There should be no exclamation point icons. An icon with an exclamation point indicates that the device is not working correctly; you need to install drivers for it. If such an icon is on the sound device, then you need to fix it.

The reason for the lack of sound can be found in the task manager.

8). Install all required drivers for your sound card. The sound processor can be installed on a separate sound card or built into the motherboard. Download the necessary drivers for the sound card from the manufacturer’s website and install them.

9). Try installing another sound card into the system unit, one that is known to work, for example, from another computer that has sound. You can ask your friends. If after these steps the problem is solved, you will have to buy a new sound card for your computer.

10). Try using System Restore to return your computer to previous state operating system. “System Restore” in Windows is located in the “Start -> All Programs -> Accessories -> System Tools -> System Restore” menu. This can help if the sound has disappeared after installing some third-party program by returning the system to the state before installing this program .

11). All that remains is to try reinstalling operating system. And first of all, install the drivers for the sound card, naturally after installing the drivers for the computer’s motherboard. There may have been a hardware conflict. If the sound appears, you can continue installing programs and applications.

The sound can disappear at the most unexpected moment. This could be either a software conflict or a hardware conflict.

12). If none of the above helped and there is still no sound on the computer, then there is only one option left - contact a specialist or take the computer to a service workshop.

Before you do anything if there is no sound or its quality is poor, remember what you did, for example, yesterday, when there was still sound on the computer. Which additional programs did you install? Surely the problem will be solved if you remove this program. Or maybe you deleted some required file from a computer. If you have not installed anything, then try the 12 steps described above to fix no sound. Surely something suggested will help you.

You can also use the Help and Support section in the Start menu.

The Help and Support section -> Music and Sound can help you find and fix the reason for the lack of sound.

If the sound is wheezing, or quiet, or something else is wrong with it, then try using the sound settings in the program. It may well be that you added some kind of effect to the sound reproduction, so the sound quality is terrible.
If there is no sound only in a certain program, then look at the settings of that program. It happens that errors occurred during installation and after reinstallation, sound appears.

Don't despair. Any problem can be resolved. Today you can buy a sound card, it doesn’t have to be fancy, sometimes something simple works much better.

Any breakdown or malfunction of the computer is unpleasant for the user. Especially often on forums people complain about a common problem - the sound on the computer has disappeared. It is impossible to completely determine the cause of this ailment without directly examining the car. But we can tell you about typical malfunctions associated with problems with sound reproduction so that you can inspect your computer yourself.

The good news is that in 90 percent of cases, computer sound problems can be resolved on your own without contacting specialized repair shops. To do this, simply follow our recommendations and advice, which we will describe in detail below.

Why is there no sound on my computer?

There may be no sound on your computer for several reasons, which can be divided into two groups: hardware and software. In the first case, the lack of sound is due to a physical breakdown of the sound card, problems with connecting the sound card to motherboard, malfunctions in the motherboard. In the second case, the problem is related to incorrect sound settings, crashed drivers, or disabling operating system sound services.

At home, we will not be able to repair a burnt-out sound card, but we can check the quality of connections between system components and the correctness of the settings without any problems. This is exactly what we will talk about next.

Incorrect sound settings

Problem. Sound settings, or rather the volume level of sound effects in various applications, can always play a cruel joke on the user, who will think that there is no sound on the computer because it is broken. At first glance, the situation seems trivial, but believe me, the volume level in the settings set to minimum is very often mistaken for a sudden breakdown. Both the user himself (by accident or carelessness) and the system (unforeseen failure) can do something wrong in the settings.

Solution. The solution to the settings problem is very simple and consists of checking the volume level in the volume mixer. You can get there by clicking right click mouse on the volume icon, which is located in the lower right corner of the screen.

In the volume mixer we check the overall volume level and the volume level in different applications. Also, don’t forget to check if the sound is muted using the special buttons.

If everything is in order with the settings, but the sound on the computer disappeared and did not appear, then read the article further.

Problem. If there are any problems connecting the sound card to the motherboard, then there will be no sound on the computer. This type of malfunction occurs less frequently than an incorrect volume setting, but it does occur. You can check whether the sound card is connected to the computer in Device Manager. If nothing is displayed in the sound devices, it means that the sound card is most likely faulty, or there are problems with the quality of its connection.

Solution. Solving this problem requires certain minimal skills in handling tools, since you will have to remove the side cover of the system unit. This must be done by first turning off and de-energizing the computer.

After removing the cover, the procedure is as follows:

• Remove the audio card from the slot
• Look at the condition of the contacts; if they are dirty or oxidized, clean them
• Check the condition of the connector; if it is dirty, carefully clean it with a brush
• If there is general dust contamination of the system unit case, it is better to clean the entire case
• Firmly insert the sound card back into the connector
• Turn on the computer, check the functionality of the audio card and the presence of sound

A loose sound card connection can be the real cause of the problem: the sound on the computer is lost, so before contacting a repair center, be sure to check the quality of its connection.

Problem. Usually personal computer represents the system unit, monitor, and connected peripheral devices (keyboard, mouse, speakers). The system unit does not have its own speakers, nor does the monitor (some models have speakers installed, but most often they do not). This means that if there is no connection between the speakers and the sound card, the user will notice that there is no sound on the computer. The first thing that comes to mind is thoughts of a breakdown or serious malfunction, but in reality the fault will lie with the speakers, which are not connected to the audio card.

Solution. If there is no sound on the computer, check the quality of the connection of the speakers or headphones to the sound card. It is quite possible that, completely by accident, the cable from your sound system was pulled out of the audio card connector.

Also, do not exclude the possibility of damage to the connecting cable between the sound card and the speakers. If such a cable is damaged, you will not hear any sounds when playing music files on your computer. If possible, check the functionality of the connecting cable.

Wrong playback device selected

Problem. If the playback device is set incorrectly in the sound settings, you will not hear sound on the computer. Let's explain with an example to make it clearer. For example, your sound card has two output connectors: a 3.5 mm line output (Rear L/R) and a digital optical output. You connect the most common 2.0 format speakers to the line output, and the playback devices are set to S/PDIF, which means using an optical cable and the corresponding connector on the sound card. In this situation, you will clearly notice that the sound on the computer has disappeared.

Solution. To solve this problem, you need to specify the playback device in the computer settings that corresponds to the actual connected equipment. To do this, right-click on the volume icon and select “Playback devices”.

The sound disappeared due to a driver failure

Problem. If you checked the volume mixer and everything is fine there, but there is still no sound, then the problem may be with the drivers. When the sound card driver stops working or starts working incorrectly, the sound on the laptop disappears. People say about this problem “the drivers have fallen off” or “the drivers have fallen down”.

There may be several reasons why a driver may start to work incorrectly:

• Viral activity
• Conflict between installed programs
• Software glitch
• Sound card driver update fails

However, we are more interested not in the causes, but in the consequences and ways to eliminate the malfunction.

Solution. Before solving problems with drivers, you need to make sure that they are the cause. To do this, go to “Start” --> “Control Panel” --> “Device Manager” and open the “Sound Devices” tab.

If there is a yellow exclamation mark on the sound device icon, then the drivers for that device are damaged. The problem with drivers can be solved by reinstalling them. At software glitch or the driver is damaged as a result of virus activity, the driver needs to be reinstalled. In case of an incorrect driver update, it is enough to roll it back. We will look at these two procedures.

1.

To update the driver, select the sound card in the device manager, right-click and click on “Properties”.

In the window that appears, go to the “Driver” tab and click the “Update” button.

Next, we will be asked to choose how to search for the driver: on the Internet or from a specified location. If you have a disk or folder with drivers for your computer, then select the second method and indicate the location of the driver. If you don’t have drivers, choose the first method.

By the way, about updating drivers. We have already reviewed an interesting article on the topic of how to update a driver using the program DriverPack Solution. With its help, you can very quickly find the missing drivers not only for your sound card, but also for other devices.

2.

As we said earlier, a rollback is performed if the driver corruption is related to its failed update. To rollback, click the “Rollback” button and in the warning that appears, click “Yes”.

If you have lost sound on your laptop and this is due to the sound card driver, then the tips described in this paragraph should solve the problem. If the problem is not in the driver, then read on.

Problem. One of possible reasons no sound on the laptop - disabling the sound card in the BIOS. This disconnection may be due to a software glitch. It is also possible that the card may be disabled by the user due to inexperience. In any case, a disabled sound card can become a real source of the problem - the sound on the laptop disappears.

Solution. The solution to this problem is quite simple. You need to go into the BIOS and enable the sound card. After this, sound should appear on the laptop. You can get into the BIOS using special hotkeys. On various laptops these keys may be different. We recommend that you read the article “How to enter BIOS on any computer.” In this article we have provided hotkeys for large quantity laptops, and you can easily find your device.

After you have entered the BIOS, you need to go to the section responsible for the operation of built-in devices. Depending on the laptop model and BIOS version, it may be called differently (for example, Advanced Features, Chipset or Intergrated Peripherals). Next, go to the “Onboard devices” section. If you did everything correctly, a list of used boards will appear on the screen. We are looking for the sound card of your laptop (for example, Realtek Audio, Audio Controller or Onboard Sound) and opposite it set the value to “Enable”, which means “Enable”. If the sound card is disabled, then the value next to it is “Disable”, which means “Turn off”.

After such a simple procedure, the sound on the laptop should be restored. If you experience any difficulties with enabling the laptop sound card in the BIOS, then describe the problem in the comments, and we will definitely help you.

If you went into the BIOS and the value next to the sound card is “Enable”, but there is still no sound, then try the method that we will consider next.

The sound on the laptop disappeared due to the disabled Windows Audio service

Problem. If the Windows Audio service is disabled on your laptop, the sound will not play. That is why it is very important to check the status of this service if you experience any difficulties with sound playback.

Solution. You can check the status of the Windows Audio service yourself, or you can contact service center. We will tell you how to do this on your own without spending money on a specialist. Press the key combination “Win+R” and enter the command “services.msc” in the window that appears.

If the “Status” field is “Stopped,” then this means. that the service is disabled and there is no sound on the laptop precisely for this reason. To start the Windows Audio service, right-click on it and select “Run”.

This will help restore sound playback on your machine. As you can see, you can check the normal operation of the service yourself and completely free of charge.

Why is there no sound on my laptop yet?

We have listed the four most common reasons for no sound on a laptop. Interestingly, troubleshooting the described problems in most cases allows you to solve the sound problem without calling a technician or contacting a service center. However, there are situations when it is impossible to repair a laptop yourself. For example, if the sound card fails or the laptop stops seeing the sound card and soldering of contacts is required. In this case, turning to a specialist becomes inevitable, since the average user cannot carry out such repairs at home.

We really hope that in your case the problem with sound was related to one of the reasons that we described, and you dealt with the breakdown on your own.

Conclusions

We have listed the main reasons why sound may disappear on your computer, and also told simple ways their elimination. We really hope that this guide will help you restore the sound to your car.

Question from a user

Hello.

I have a problem with my PC: there is some kind of extraneous noise coming from the speakers and headphones (reminiscent of crackling). I poked the wires - it didn’t help; I also rearranged the inputs - the problem did not go away. By the way, if you click the mouse, this noise intensifies a little. What to do?

Built-in sound card, Realtek (I don’t know the exact model). The headphones are new, the speakers are very ordinary, although they are already quite old (7-8 years old).

Good day!

In general, there can be a great variety of noises encountered in speakers and headphones: for example, the noise of a mouse wheel, various crackling sounds, whistling, intermittent and trembling noises, etc. They can appear for a variety of reasons.

The user problem with sound described above is quite typical (unfortunately), and it is not always so easy and quick to fix. However, in this article I will try to give all the most important points that you need to pay attention to first. By eliminating them, with a high degree of probability, you will make your sound better and cleaner.

If you have sound too quiet- try the tips from the following article:

If you have no sound at all on a computer - I recommend reading this guide:

Causes and elimination of extraneous sound in speakers and headphones

Cable for connecting speakers/headphones

1) Is the cable intact?

Many people don’t attach any importance to this (supposedly what will happen to it), and the cable, by the way, can be damaged accidentally: if you move furniture carelessly, bend it, or step on your heel. In addition, many people have pets in their homes. In general, there are enough reasons without your direct intervention...

The photo below shows a damaged audio cable...

2) Broken audio connectors

Over time, any audio connectors begin to “weaken” (most often from intensive use) - and the plug is not clamped tightly into them, sometimes there is even a slight play (gap). If in this case you try to insert/remove the plug and twist it in the socket, you may notice how noise appears in the speakers and how they disappear. In this way, you can choose a position for the plug that will not produce noise. The cable can be secured with tape in this “ideal” position.

In general, if the problem is with broken sockets, replace them in the computer. service, the question is not too “expensive”.

3) Cable length

I also want to pay attention to the length of the cable. If computer speakers are located 2 meters from the system unit - then using cables 10 meters long is unreasonable (especially if there are some adapters or extension cords). All this can cause “distorted” sound, a kind of interference. In general, I do not recommend using cables longer than 2-5 meters (in the most common situations, for household use).

4) Is the cable fixed?

Another reason that I had to deal with was the following: the cable from the system unit to the speakers was suspended, about 2 meters long. Naturally, if the window in the room was open, then the draft caused this cable to “dangle” and extraneous noise was observed.

Getting rid of the problem was very simple: using ordinary tape, we attached the cable in 2-3 places to the table and the noise disappeared.

By the way, the cable can also be touched by passing people (if your PC is not very convenient), pets, even your own legs (if the cable runs under the table). Therefore, my advice: secure (fix) or lay the cable so that no one touches it accidentally.

The photo below shows special holders/clamps that prevent the cables from getting tangled and prevent any wires from dangling. These Velcro holders can be placed at the back of the table and secure all wires and cables. By the way, you can use regular tape instead.

5) Front and rear audio jacks

Another important point: if laptops have only one audio connector (usually on the side panel), then the system unit has 2 of them (most often): on the back of the unit, and on the front.

Many users find it more convenient to connect headphones (sometimes speakers) to the front side of the unit - and often in this case the sound is not as high quality as if you connected it to the audio connectors on the back wall of the system unit. This is due to adapters, extension cords, and other issues with connecting the front panel (from the rear of the system unit - the audio outputs go “directly” from the sound card).

In general, the motive behind this advice is simple: try connecting headphones/speakers to the audio outputs on the back wall of the system unit.

6) Is the cable intertwined with other cords?

Also, background noise and extraneous noise may appear in the speakers due to the fact that the audio cable is too “tightly” intertwined with other wires. Try to carefully position it so that it is away from the rest. By the way, this advice overlaps with fixing the cable (see just above).

And one more tip: If you experience hissing and noise in your speakers, try connecting headphones instead (or vice versa). This will not solve the problem, but it will help find and diagnose the cause. If there is no noise in the headphones, then the reason probably lies outside the system unit (which is already something...).

Incorrect sound settings in Windows

Often, extraneous noise in the speakers is associated with not entirely “correct” sound settings in Windows. Therefore, I recommend trying to change them...

To do this, open the panel Windows management at: Control Panel\Hardware and Sound .

It will display several of your audio devices. Open the properties of the one through which there is a sound by default (such a device is marked with a green checkmark).

Note: by the way, if the default device for sound playback is selected incorrectly, you will not hear sound.

When will you open speaker properties(default playback devices) - look at the "Levels" tab (see screenshot below). In this tab, reduce all extraneous sources to a minimum: PC Beer, CD, Microphone, Line In, etc. (their number and availability depends on your computer configuration).

Next, I recommend opening the tab "improvements" and see if it is enabled "Loudness of Compensation" (by the way, in some versions of Windows it is called " Additional features/volume equalization").

Save the settings and check if the sound has changed or become clearer.

Lack of current sound driver/driver settings

In general, usually, when there are problems with drivers, there is no sound at all. But modern Windows versions(8, 8.1, 10) install drivers automatically. There is nothing wrong with this; on the contrary, they make life easier for novice users. But there is one big “BUT” - the drivers they install usually cannot be configured, i.e. there is no extra panels where important parameters for your equipment are set. As a result, certain sound distortions may occur.

In order not to repeat ourselves about how to check if there is an audio driver in the system, how to find and update it, how to remove it old driver etc. - I recommend reading this article:

You may also find programs for automatic update drivers in the system. I talked about them in this article:

I also recommend paying attention to the settings of the driver itself. To open audio driver settings: go to the Windows Control Panel in the section "Equipment and Sound" . Further at the bottom of the window, there is usually always a link to the settings: in my case, this is "Dell Audio" (in yours, for example, this could be Realtek Audio).

In the audio driver settings, check the volume of the main devices (play around with it), disable various “obscure” enhancements, filters, etc. Very often they are the cause of all sorts of sound problems.

Checking speakers on another PC

If the above recommendations do not give any effect, I highly recommend connecting your speakers or headphones to another device: laptop, TV, PC, etc. This must be done in order to determine the source of extraneous sound:

- either it’s the speakers’ fault (if the sound on other devices is noisy);

- or the system unit itself is “to blame” (if the speakers behave normally when connected to other sound sources).

The reason may be grounding...

Grounding (sometimes called grounding) in ordinary residential buildings, most often, this is done in the basement. All sockets in the building are connected to this ground. If all equipment (including speakers) is connected to the same outlet, then problems with interference due to grounding usually never arise.

If the noise is caused by grounding, then the easiest way to get rid of this is to connect all equipment to the network through one common power socket. It’s even better if a surge protector (not Chinese, but standard quality, or UPS) is connected to the outlet, to which the PC and speakers will be connected.

The photo below shows a surge protector for 5 outlets. Enough for most ordinary home PCs, you can connect: a monitor, a system unit, speakers, a printer, and there’s also room for a phone charger...

Important! In the absence of grounding, some authors recommend connecting the system unit case to a regular battery. I categorically do not recommend doing this (if the network is built in a certain way, you may get an electric shock)! In general, the issue with grounding is best resolved with an electrician.

Noise from mouse wheel scrolling

Sometimes the noise from scrolling the mouse wheel gets into the audio interference and is heard in the speakers. Sometimes such noise can be quite strong and it is simply impossible to listen to music while working.

If you hear sound from the mouse in the speakers, then I recommend taking the following series of measures:

Try replacing the mouse with a new one;

If you use a mouse with a PS/2 connector, replace it with a USB one (or vice versa);

You can also use PS/2 to USB adapters. For example, by connecting a mouse with a PS/2 connector to a USB port;

Try using a wireless mouse.

The photo below shows: a mouse with a PS/2 plug, a USB mouse, and adapters from PS/2 to USB.

Mobile phones and gadgets

If your mobile phone is too close to the speakers, then when you call it (or receive an SMS), you may hear a strong crackling sound and interference. You can, of course, try to shield the audio cable, but at home, in my opinion, all this is a waste of money, time and effort.

The best way out is to find a place for your mobile phone that is not on the computer desk, or at least place the phone and speakers in different corners. Thanks to this, crackling and noise will be significantly reduced.

By the way, this can be observed from walkie-talkies, radiotelephones and other similar gadgets and set-top boxes. Anything that has an antenna and radio signals can potentially be the source of the strongest vibrations reflected in your speakers.

In some cases, even an ordinary printer/scanner/copier or an “unusual” desk lamp can cause noise in the speakers. Therefore, at least for the duration of the diagnosis, I recommend turning off any extraneous devices located near the speakers one by one and monitoring the condition and purity of the sound.

I think there is nothing more to comment here...

High volume on low-quality speakers

Volume above 50% on inexpensive low-quality speakers (and headphones) may well be the cause of noise (they say that the speakers are starting to make noise).

In general, all speakers and headphones produce noise. True, higher quality speakers (and, as a rule, more expensive ones) produce more clear sound even at high volume, and the noise is only at maximum. While cheap ones - when the volume reaches medium levels...

Also pay attention to the microphone. If your speakers are turned on loudly and the microphone is working, then a closed “ring” effect may be observed.

Low power supply (Eco mode)

This tip is more suitable for laptop users...

The fact is that laptops have several operating modes: economy mode, balanced mode, and high performance. Manufacturers do this in order to use battery power more economically.

In some cases, reduced power consumption does not allow for high-quality sound. Therefore, I recommend going to the Windows Control Panel: Control Panel\Hardware and Sound\Power Options . Then turn on high performance and save the settings (see screenshot below).

Installing an external sound card

For some reason, many people think that an external sound card is some kind of large device, expensive, etc. All this is a thing of the past; now there are modern sound cards, the size of which is slightly larger than a USB flash drive (and they look almost the same).

Yes, you cannot connect any specific equipment to such a sound card, but you can connect ordinary classic headphones and speakers, and a microphone to it, which is more than enough for many average users.

In addition, an external sound card can simply help out and help get rid of extraneous noise when other options did not solve the problem. Moreover, the cost of many models is more than affordable (the cheapest options cost no more than a few hundred rubles).

The photo below shows a USB sound card. Such a small “baby” is capable of producing fairly high-quality sound that will be the envy of some built-in sound cards. And in principle, it will suit most users who are satisfied with the most “ordinary” sound.

That's all I have. Additions on the topic are welcome...
