Thanks, you've saved me a slow terrible suicide...
I tried alsamixer some time ago and got somekind of error and it
didn't run.  I don't think I've tried it since.  That was all I
needed.

Took a little mucking around to figure out what stuff did what.

Only remaining thing I see wrong is that the output isn't near as
clear and staticless as it is when these speakers and sound card are
used on a windows xp machine.  They are just junkyard powered
computer speakers but sound ok when connected to a different
machine.  So must be the signal coming to them is different somehow.
