Ah, pushed. Sorry about that. > /dev/mixer is normal, but if you have 2+ audio cards or OSS4 things > are different (not sure if OSS4 would work with this, though). Would the multiple audio cards show up as channels, or as dev nodes? (I can't say 'devices' because the OSS terminology and the traditional unix terminology _both_ use that.

That's why I didn't make mix output the volume by default: scriptability. (The Unix Philosophy by Mike Gancarz should be required reading.
