The first think I'd try next is to run alsamixer and make sure the volume
is turned up.
Check.
Next, try to play a sample sound using aplay. If you get
any errors, post them. If you hear no sound with aplay, try the '-v' and
'-vv' switches. The last one should show continuous output for a while.
Progress! Aplay at least generates sound--the first peep I've heard from
the system since I installed. Here's a sample output:
harvey@doob:~$ aplay -vv /usr/share/sounds/pop.wav

The only other thing I can think of is that the OSS driver might be
built into your kernel. I don't know if this is a Debian practice or not.
What kernel are you on? (uname -r)
harvey@doob:~$ uname -r
2.6.8-powerpc
Thanks for your help--at least now I know the system is capable of
sound. Any idea why the cd player, though clearly playing a music cd, is
not generating any audio? (And I still can't ring the system bell?)
