I tried this, to no avail.  Here's what I did.

1) Fired up FC 3 and logged into KDE.
2) Kicked off xmms with the KDE_Desktop1.wav (staticy noise can be heard
from the speakers, I have it on repeat so it just keeps going).
3) I opened KMix at first and tried to adjust things.  The only two
controls that have any effect were PCM and Main Volume.
4) I then opened alsamixer and scrolled to the very far right.  And
reduced *everything* or muted it (if I could) moving back to the left.
Nothing effects the sound until I get to WAV, PCM, and Main Volume.
Every other control is at zero or muted.

Seems that the Toshiba's just don't want to play nicely with the sound
control stuff I guess.  I find it fascinating that in one of the FC2
kernels (I upgraded with yum) it started to work.  Needless to say I was
shocked, but at the next kernel upgrade it stopped working.

Thanks for the help.

cheers
