I recently built a custom PC, and everything worked fine initially. However, I started noticing a strange white noise or buzzing in my headsets that only occurs when I move my wireless mouse, which connects via a dongle. I've tried relocating the dongle to different USB ports, disabled Bluetooth and WiFi, but the problem persists. When I switched to a wired mouse, the noise stopped. Is this likely due to an issue with the dongle or something with my PC? Thanks for any insights!

It sounds like you're experiencing electrical interference, which is pretty common with USB devices, especially when using a wireless mouse dongle. The fact that the noise only crops up when moving the mouse indicates that it might be interference that's affecting your headphone audio. This is often seen with USB 3.0 ports. You might want to check if using USB 2.0 makes a difference, or try to keep the dongle as far from the audio outputs as possible.
Since you mentioned that the headset worked fine on another device, it seems like a compatibility issue with your current setup. The interference could be coming from the USB port. If you haven't already, test your headset on the rear audio outputs of your PC. Sometimes front panel outputs can introduce noise. Otherwise, investing in a USB audio adapter can help isolate the power supply noise from your headset.
If your headset is wired, try moving the dongle further away from the headphone cables. If it’s wireless, you're likely dealing with frequency overlap, and there’s not much you can do besides finding a better quality wireless headset or a different mouse. If the noise continues while using the mouse, it might be best to look for a USB headphone adapter, which can help bypass the issue.
