If you’re using a desktop PC, you might have heard odd noises coming from your speakers or headphones at times. It may sound like a buzzing or whining when doing basic tasks, sometimes escalating with more intense use like games or streaming movies. To solve the problem, you’ll need to figure out what’s causing it.
Where Speaker Noise Can Come From
There are dozens, maybe hundreds of explanations for unwanted sounds coming from your speakers. Luckily, the most common issues are fairly obvious. Broadly speaking, we can break them down into three categories: problems that originate from the physical speakers, the cable connection, and from the PC itself.
It’s easy enough to nail down which part of your speaker setup is at fault. To see if the speakers are the problem, simply plug them into an audio source other than your PC—like a phone or an MP3 player. Note that it’s perfectly normal to hear pops and buzzes as you disconnect the audio jack and plug it into something else, but if you continue to hear electronic interference even after plugging it in, you can rule out your PC as the problem. You can perform the same test in reverse, too: get another set of speakers or headphones and plug them into your PC. If you still hear the unwanted noises, your PC is likely to blame.
If the problems continue (and it’s possible to use another cable with your speakers or headphones), then try replacing the cable. If you hear clearer sound with no interference, then the cable was the likely culprit. Usually this means that either the connector on the end has some kind of physical defect causing a poor connection with the audio source, or the cable itself is poorly shielded. What you’re hearing is electromagnetic interference from your PC or other electrical devices in the room. The fix here is simple enough: just use a different cable, preferably one with a high-quality jack and better shielding.
If the speakers are the problem, it’s likely that they’re damaged. You might be able to isolate specifically which speaker is damaged by listening closely, especially if…
