How to Fix Buzzing Noise from Speakers When Playing Games

Do you have a buzzing noise coming from your speakers only when you play games? This can be a frustrating problem to deal with, but fortunately, it is one that can be fixed.

In this article, we will discuss the causes of this issue and how to fix it. Keep reading for more information!

Incorrect Audio Settings

One of the most common reasons for this problem is incorrect audio settings. Many gamers forget to change their audio settings when they start playing a new game.

As a result, they end up with a sub-optimal sound quality that can cause buzzing or crackling noises.

To fix this, simply go into your game’s audio settings and make sure that the settings are optimized for your specific hardware and environment.

For example, if you’re playing a game on a laptop, make sure that the “Laptop Speakers” setting is enabled.

Change your Audio Bit Rate

I was playing DayZ one day and I started to notice that my speakers were buzzing only when I was playing the game. I wasn’t sure what was causing it, but I knew that it was really annoying.

I did some research online and discovered that the problem might be caused by my audio bit rate setting.

I changed my audio bitrate from 16-bit to 24-bit and the buzzing stopped. If you’re experiencing this problem, I suggest that you try changing your audio bit rate as well. You might be surprised by how much of a difference it can make.

Enable V-Sync

It’s quite common practice nowadays to disable V-Sync as soon as you load up a new game.

However, doing so can sometimes cause audio problems like buzzing or crackling.

It may not be your speakers making the buzzing noise, it might actually be your graphics card. V-Sync works by synchronizing your frame rate with your monitor’s refresh rate. This can help to eliminate screen tearing and it can also reduce input lag.

However, most modern PC’s run at high FPS on most games now, but it can cause coil whine.

Coil whine is a high-pitched noise that is sometimes caused by graphics cards. It’s most noticeable when the card is under load and it can be pretty annoying.

If you’re experiencing coil whine, try enabling V-Sync to see if it fixes the issue. If it does, then you might want to keep it enabled.

Frequency Interference

Another possible cause of the buzzing noise is frequency interference. This can be caused by electrical equipment that is close to your speakers.

To fix this, simply move your speakers away from any electronic devices. If that doesn’t work, try using a different outlet or surge protector.

Audio Driver Issues

If you’re still having problems with your speakers buzzing, it’s possible that you have a driver issue.

Outdated or corrupt audio drivers can cause all sorts of problems, including crackling or buzzing noises.

The best way to fix this problem is to update your audio drivers. You can do this manually by going to your audio card manufacturer’s website and downloading the latest drivers.

Alternatively, you can use a driver update tool like Driver Booster to automatically download and install the latest drivers for you.

I also recommend you install your latest graphics card drivers too in case they are causing some sort of issue.

Sound Card

It’s also possible that your sound card is the root of all evil. This isn’t as common of a problem as it used to be, but it still does happen from time to time.

If you think that your sound card might be the source of your buzzing noise, try disabling it in your audio settings.

If the noise goes away, then you know that your sound card is the problem. You can try updating your drivers or purchasing a new sound card if necessary.

Cheap KVM Switch Cable

Another common issue that causes your speakers to buzz only when playing video games is using a cheap KVM switch cable.

A KVM switch is a device that allows you to use one set of keyboard, video, and mouse (KVM) with multiple computers.

They are often used by gamers who have multiple gaming consoles.

The problem is that some cheap ones have poor shielding. This can cause interference and noise on the audio line.

If you’re using a KVM switch, try upgrading to a better quality one. It might cost a bit more, but it will be worth it in the end.

Try a different audio input

Sometimes, audio headers on your computer case can have poor built-in headers for audio. These can cause various issues, one of them being speakers buzzing.

Computer Case Audio Inputs

It can also cause interference if the audio cables are running near one of the power cables inside your case. This is most likely caused by cable management inside the case and using cable ties to tightly pack them together.

While it looks great and clean, it may be the cause of these audio problems.

Invest in an external DAC

If you want to get the best possible audio quality from your speakers, you should invest in an external DAC/AMP.

DAC stands for digital-to-analog converter. This converts the digital signal from your computer into an analog signal that can be amplified.

An AMP is a simple amplifier that takes that analog signal and makes it louder.

A good quality DAC/AMP will make a world of difference in the quality of your audio. It’s definitely something to consider if you’re serious about your gaming or music listening experience.

It can also fix your problems by avoiding cheap audio interfaces built into the motherboard or your computer case.

Electrical ground looping within your PC

One final thing that can cause your speakers to buzz only when playing games is an electrical ground loop within your PC.

This is most likely caused by the way your computer case is grounded. If you’re not sure what I’m talking about, it’s basically a short circuit between two pieces of metal that are supposed to be at the same electrical potential.

This can cause a small current to flow between the two pieces of metal, which in turn can cause your speakers to buzz.

The fix for this is to either use an isolation transformer on your AC power line or to use a “ground loop isolator” between your computer and speakers.

Both of these devices will break the ground loop and stop the current from flowing, which will then stop your speakers from buzzing.


It’s possible that one of the many issues we’ve talked about in this article is causing your speakers to buzz only when playing video games.

We’ve provided a number of solutions, so hopefully, you can find the one that best fits your needs and fixes the problem.
