This is a physically large 2 Xeon desktop, so it would really nifty if I
could rewire it as a laptop!

I just tried the headphone socket:  same behaviour.  "mixer vol" has no
effect.  I'll just ignore it;  it seems that applications know to adjust
"pcm".

The real issue is knowing to increase "ogain" to get a reasonable base.
