/dev/dsp is not being held open. I've checked with fuser, and no
program is reported to be using it. Does lsof do basically the same
thing? I'll check on that. Have never used lsof before.

The mixer settings all look okay -- both for btaudio AND the nforce
audio. I've used aumix AND kmix (aumix doesn't see the btaudio for some
reason). Any other programs to try? Are there any other settings aside
from volue controls I should look at?
The line-out on the WinTV card works properly. I've checked it by
directly connecting it to my stereo system and output is fine. NONE of
the inputs I've checked on the card work properly. Mic, Line-In, or
CD-IN. I've used both the nvaudio and the i810 audio drivers and the
same thing happens for either.

This fixed the squeeky mp3 problem. Thanks!
