High Pitched Noise From Computer Speakers

With further testing the high pitch noise seems to be caused by both when the breathing illumination is active, and microphone is unmuted. The noise is also comming from the left speaker. When charger is plugged in, the noise is not there. Jul 12, 2017 - You may experience distorted and high-pitched sound coming out from your laptop's speaker or even if you plugged the earphones or headphones. The faulty audio and sound configuration can cause this sound problem or may be your sound driver is not updated one or your playback devices settings are not correct. For a week or two I was only aware of the high pitched whine through the speakers, then it became audible from the case with the speakers off. After another week or two it was audible with the computer off, and at that point it became apparent that the noise was coming from the PSU.
High Pitched Noise From Computer Speakers When Nothing Is Playing

Hey, I could use your advice.Recently I bought the Logitech Z623 because I needed some relatively cheap and easy speakers for my setup. I plugged each speaker into the subwoofer and plugged that directly into the wall.I'm running a 3.5mm aux cable from the sub into the back of my PC. I've got Realtek HD Audio drivers installed, latest from their website.Despite doing everything right, I still get a high pitched frequency coming from both speakers even when not plugged in and the volume turned all the way down. It's rather annoying and unfortunate that I can't fully enjoy my new speakers. I wanna try everything before I contact Logitech for an RMA, so any ideas?. The issue may be a janky electrical setup. Noise coming over power lines is possible, and is most often caused by an improper (or complete lack of) grounding.
Try using them in a known-grounded outlet. In a home, this is most commonly found by identifying a ground-fault-interrupter outlet. These can be found in bathrooms most often, and they will have a test/reset button on them kinda like you'd fine on a hairdryer.If your house does not have a ground anywhere because the electrical hasn't been updated in forever, just take them to some random public place, such as your office or school, to test them.
Yes I did the exchange, new set works 100% fine. All I had to do was print off the return label, put the old brown Logitech box back together (tricky), and take it to a UPS store.One thing I found when testing was that it was not the right speaker causing the problem. I connected the new right speaker to the old subwoofer and it still didn't work. However when I connected the new right speaker to the new subwoofer, it worked. To me this shows the problem is actually in the subwoofer. Be sure to test all the new equipment without using any of the old components.
