Oh, I might have been too vague there. I can't exactly reproduce the old
state because I changed much of my other hardware in this machine since and
my old kernel images won't boot; and then I also noticed that there was once
an old OSS driver and then I switched to alsa, but I don't have backups of
my ancient /etc/modules file so I don't know when that was.
I re-selected the old-style i810_audio driver in 2.6.21 and compiled it,
unloaded the ALSA driver, loaded the old driver, and voila, everything went
back to normal, I can hear the TV sound just fine. So, it might be that this
is an OSS->ALSA regression that slipped through the cracks?
