hey folks im not too familar with the alsa device number scheme or where
this info is stored. i think there is a /proc/ that will show me
something like this but i cant find it

device 0,0 card a output a
device 0,1 card a input a
etc
etc

i got multiple sound cards in my machine, and the ubuntu 9.10 mixer
really dumbs things down

thanks

I’m missing a exact question, so I guess:

Q: Where do I find the device names that ALSA knows of?

A: Try ‘aplay -l’. This should give you some things you can try out.
If your card is not supporting your desired smapling frequency and you
were using hw:x.x, try hwplug:x.x instead.
