Hello! I know this issue has been posted quite a few times, but I'm finding difficult to parse through all the posts.
I have a Topping A90 amp connected to my PC by USB. When I turn the volume up and/or set the gain to "high", I get an irritating static sound. This sound also seems to be effected by mouse movements. I've read that it is a grounding issue, but I'm somewhat a novice on the topic and would love help.
I've purchased an optical cable to try that instead of USB. I'll update my post when it arrives.
