[QUOTE="bowser, post: 485929, member: 31775"] I've been suffering from unbearable microphone background noise. I'd describe it as a buzzing more than a hiss. I have a desktop PC plugged directly into the wall, and a microphone connected to that via USB. Whenever I touch and hold the bottom of the PC case, the buzzing goes away and returns when I let go. A few vaguely similar posts on various forums suggest this could be due to a "grounding problem". I purchased a socket tester ([URL="https://www.amazon.co.uk/gp/product/B07NRTC77S"]this one to be specific[/URL]) and it reports no issues, although it does note that it can't detect a reversed ground and neutral. Does anyone have any ideas on what this could be or further steps to diagnose it? Thanks! [/QUOTE]
