I know this is probably hardware-specific rather than ALSA-specific, but I was hoping someone could point me in the right direction here... I have: Guitar -> Behringer Xenyx mixer -> M-Audio Audiophile 2496 RCA inputs When the setup is sitting there, idle and active, there is a very very high-pitched light squeal coming from the PC speakers. It's so high-pitched that only myself and so far two other people I've had listen can hear it. However, when I touch my hand to the guitar strings, the squeal completely disappears. To me this sounds like a grounding issue, but I'm able to reproduce this across several different guitars with different pickups & pickup arrangements. Any ideas? ---------------------- Wade Nelson hollywoodb@xxxxxxxxxxx "I may have to share this planet with animals, but I'm doing my damn best to eat every last one of them." ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
