here's the issue I'm experiencing: I plug an audio source in my board, I can hear everything clean, I capture the sound (using Audacity), but when I play it back it sounds terribly hissy and noisy...
I have no problems with audio output from files instead, e.g. using xmms or mplayer. I'm on Fedora Core 2 with ALSA, but I had the same problem even on SuSE Personal 9.1.
Thanks in advance!
