try "alsamixer" which should be part of
alsa-utils. Or you can try
"amixer", more powerfull but a bit more complicated.

Oh - my mistake was to download only the alsa-driver package.
I didn't realize alsa-lib and alsa-utils, too, were needed.
OK, I downloaded and installed them. But...
First, I tried DVD and TV. Well, it seems 'xine' needs an
audio plugin for alsa. It now only has plugins called 'oss'
and 'esd.' No sound.
Then I tried 'alsamixer'. It does show the correct title
VIA 8233A/C
Avance Logic ALC650 rev 0
and a collection of bars. The meaning of many of them is unclear
to me, but I tried to up the volumes on most. Unfortunately, when
I tried to play a MIDI file with 'aplay', no sound resulted. I
also downloaded and tried the old 'playmidi', but it doesn't
find '/dev/sequencer'.
