Thanks.

Only "mixer ogain" and "mixer pcm" change the actual volume on this machine.
"mixer cd" does affect CD playback volume, but I need to increase ogain from
the default 50:50 to get an acceptable volume.

"mixer vol" has no effect;  the actual volume stays constant as I change the
volume from 0 to 100.  This seems like a bug, but perhaps I'm missing
something.
