I've tried the cd players that come as a standard part of KDE (KsCD) and 
Gnome. Haven't been able to get into any of their config files, at least 
not in the gui. And while they both readily play music cd--no sound.

One very interesting development: I discovered I have Totem dvd player 
on the system, so popped in a dvd. Surprise! movie played--with sound!

Thanks for the tip. Here's output:

While playing a music cd in KsCD [no sound]:

Lot more going on with the latter, but I don't know how to interpret the 
results. Main thing I notice is that /dev/snd/pcmC0D0p is now in on the 
act as well as /dev/snd/controlC0.

Here's the contents of the /dev/snd directory:

harvey@doob:~$ ls -l /dev/snd/
total 0
crw-rw----  1 root audio 116,  0 2005-01-09 18:18 controlC0
crw-rw----  1 root audio 116, 16 2005-01-09 18:18 pcmC0D0p
crw-rw----  1 root audio 116, 33 2005-01-09 18:18 timer

I don't know why "total 0" when there are 3 files listed. But I know 
that "c" implies a character device, assisting communication betw kernel 
& hardware devices.

That's good info to have. I don't espec want the system bell around--was 
just using it as a way to test for sound.

Any idea based on the above where I might go from here?

Thanks again, Martin.
