Done: http://code.google.com/p/emutrix/

Also added a few tests and some "sane" defaults.

Warning: if you run it, it will turn a lot of your levels down, and some
up. Should be easy to correct afterwards with alsamixer, but to be on
the safe side, store your driver configuration with

alsactl -f mixer.bak store

before testing.

It is also worth mentioning that the program ignores all those pesky
"PCM Multichannel Routing/Volume" and similar mixer elements. If they
are not set as per driver default, it may not work. If someone has any
idea how those work, please explain.

Greetings,
Camilo
