Re(2): No Sound Card found on Testing Install
 
This morning in accordance with the last paragraph in
http://wiki.debian.org/DebianMultimedia/FAQ
I removed the line
deb http://www.deb-multimedia.org squeeze main non-free
from /etc/apt/sources.list .

After updating the system and rebooting, Iceweasel produced no sound.
According to http://www.opensrc.org/FAQ026, the following
/etc/asound.conf should make the C-Media USB Headphone Set
the default sound device. No such luck. Iceweasel still produces no sound.
Either the audio data is sent to the SiS chip, which has no speaker, or something
more obscure happens. In Twinkle, sound is fine as always.

Pertinent information follows. Suggestions welcome.
Thanks, ... Peter E.

On further testing, some videos yield sound, others do not.
This report appears to be pertinent.
