Hey, I'm trying to resolve teething issues on a new motherboard,
Sound plays but I can't configure it with alsamixer, I need to boost the
gain before I have to solder together a +6db line amp...
Alsamixer dies with following when I try to configure "card 2"
tg@tortoise ~ $ alsamixer
cannot load mixer controls: Broken pipe
