Audacity Forum

I've tried wiggling connectors, moving the pc to a different room and changing every component I could feasibly try (microphone, graphics card, psu). Nothing removed or even changed the sound. The only thing left to blame is a bad soundchip on the motherboard, I think it's RMA time.

While recording anything through my mic on my PC I get this weird squeaking/squealing noise (see link below for sound clip). It's not the mic and not a driver related issue (tested with multiple drivers in windows and linux). Anybody got any ideas? Is it interference, should I try a PSU change or is...
