i see.  so i guess there's no per-channel device node under alsa?

gotcha.  alsa-aware apps it is, then.  thanks.

if alsa is doing the mixing, how can one adjust the relative
volume of the inputs?  possible?  going back to my music and
home-automation menuing example, i could see wanting to mute or
reduce the volume of the music while the voice menus are
speaking.
