I think I need a sound/ALSA guru.

Hi;

I tried your suggestions yesterday.  Here is what happened.

How can I tell for certain that my TV card also has an intrusive mixer?
I have looked in tvtime and bttv as well as asound.conf and I couldn't
see anything that looked like an additonal mixer -- but then what do I
know?

I am not sure what you mean.  I am going to try experimenting
configuring asound.conf with all the suggestions I have received.
Didn't seem to help before, but maybe now that I have added the lines to
my modprobe.conf the changes will stick long enough to tell me
something.

Ran gst-register-8.0 once again.  Changed nothing.

asound.conf remained unchanged both before and after my ATI TV card was
removed, and after it was returned. Kudzu was on.

audacity could still not find the i/o.
cd plays even when CD in mixer is off.

Wrote similar lines in my modprobe.conf.  There is some debate over
whether it is necessary in FC4.  I found that it prevented my mixer
settings from being changed -- I think.

Distortion issues fixed.  See earlier post to Alexander.
