Umm... don't remember. Soon as I get Debian back on, I'll let you know. Don't think it was anything tricky.

You try with -c $WHATEVER yet? There are 2 alsa interfaces, IIRC. One is boring. The other is interesting, and lets you play out the speakers, headphone jack, and BT (HSP) all at once. The sync between HSP and speakers/phones is a little annoying, but it's kinda cool. Especially if you have the car stereo drowning out the headset (when you're in the car), but when you leave the car, you still hear it with the headset. (Obviously, the correct way to accomplish this balance is to turn the headset down, not the stereo up; hearing loss isn't fun and all that.)
