[CM] SND specifying audio devices

[Garett Shulman]

Hello, I am trying to use snd with an maudio 66 which has 10 channels of 
I/O. This causes the record window to extend well below my monitor 
(which is running at 1280x1024). I have a plug device defined in my 
asoundrc named 66_12 which is a 2 channel subset of the I/Os on my audio 
hardware.

I have been trying:
export SNDLIB_ALSA_PLAYBACK_DEVICE=66_12

and:
export SNDLIB_ALSA_RECORD_DEVICE=66_12

However, the record window still includes the full 10 channels for input 
and output. I noticed that you can adjust the size of the meters. 
However, I am not sure this will solve the problem as the sliders for 
all the channels also take up a significant amount of screen realestate.

Questions:
Are environment variables the best way to specifiy an alsa device for 
audio I/O?
Is there a list of environment variables that snd recognizes documented 
anywhere?
Is there another mechanism to limit the channels that snd uses for audio 
I/O?

Thanks for any suggestions that anyone might have.

BTW, snd seems very cool: an audio editor based on emacs that you can 
extend with lisp and have to recompile to configure... it's so geeky. ;)
