Airport delays. Parking Costs. People driving really, really close behind you. These are all on the long list of things that are super annoying that we really have no control over.

But if there’s one thing that really grinds my gears, it’s when you sit down to work on your computer, and your speakers are buzzing.

Fortunately with buzzing speakers, there are a few things that you can do to prevent this from happening. And if you know how, it can be pretty easy to deal with.

Yes, it’s still annoying. But, it’s something that you can undoubtedly prevent if you can manage to avoid frequency interference.

Depending on what speakers you’re using – whether they’re connected to your computer or your television – there’s different ways to resolve each issue.

So, we’ll take a look at the easiest ways to try and stop your speakers from buzzing.

Stop Speakers from Buzzing – Computer

Probably the most common time that your speakers will start buzzing is through your computer, which is actually the most likely scenario for most people.

An annoying buzzing sound can distract you, and it’s likely down to frequency interference at some point down the line.

When using speakers with your computer, this can happen frequently. Fortunately with computer speakers, there are some pretty easy resolutions that might fix your problem.

Step 1 – Check Connections


Undoubtedly the first thing that you want to do with your computer speakers is check all of the connections. Even though you’d think this wouldn’t be an issue, often this is the cause of any form of buzzing.

This means taking the cables out and potentially cleaning them if necessary. This should allow you to ensure that cables definitely aren’t the problem.

Step 2 – Determine the Cause

Manoeuvre the wires a little whilst they’re plugged in. This can help determine what the actual cause of your speakers buzzing is, as often you can identify a buzzing noise by moving the parts of your audio device around.

If the hum is not consistent, then this could indicate that there’s a problem with the wires (this can happen with cheaper computer speakers).

Step 3 – Extension Cables

Is your computer plugged into the wall directly or is it using an extension cable? If it’s using an extension cable, then try it directly plugged into the wall.

Any default audio device can have issues if you don’t directly connect the speakers to the power supply. An extension cable is just another area where your connection could cause a hardware issue.

Step 4 – Check RF Transmitters

Ensure that your speakers aren’t close to your wifi router, or any other form of radio frequency transmitter that might be having an effect on your bussing speakers.

If your speakers sound as ‘crackly’ as they do buzzy, then this could be a cause.

Step 5 – Download audio driver

Download an update or a new audio driver. An outdated audio driver can be an undoubtedly cause of buzzing speakers, so this is something you’ll want to check out.

For most people, it’s really easy to update your audio drivers and this shouldn’t be too difficult. If you don’t want to do this, then there are programs that you can download which can help you do it.

Step 6 – Fiddle Around with your Computer Settings

Finally, you’ll want to have a play around with your computer settings.

This can help to isolate down your issues to see whether it’s a problem with a specific speaker, or whether the buzzing sound may be down to an issue with the software you’re using.

For example if you’re on a Mac computer, you can head into System Preferences and go through to Sound.

Here, you have the option to isolate the sound of your speakers to one or the other through the Balance.


When you’re in your settings, move the pointer to both left and right. This will isolate the sound to one speaker or the other.

This is pretty much the same for any laptop or computer, whether you’ve got your speakers plugged in or not. It will allow you the ability to ensure where the problem may be.speakers-buzz-2


If you’re having troubles with your computer speakers, then these are the best ways to try and deal with them. If nothing here helps to solve your issue, then the likelihood is that you’re going to have to take your speakers in for some repair work.

You can also look for any audio enhancements within your audio settings too, which should help you to resolve any buzzing sound issue.

This isn’t the end of the world, as often speaker repair work is fairly cheap. But, do this before you go and take your speakers there for no reason!
