By the way, that link is really good.  It did confirm that I'm using the
correct driver.  I checked the plugs and nothing.  I think I might try
another sound card.  The one I've been trying to get working is part of
the mother board.  I'm sure I have a Sound Blaster around somewhere.
I'll let you know if that maks a difference.

. . . and yes I have the following.
# ls -al /dev/snd/
total 0
drwxr-xr-x  3 root root      240 Jan 21 12:49 .
drwxr-xr-x 15 root root     3880 Jan 21 12:50 ..
