Hi Brad,

Yeah, but this covers A2DP only, right?

Right now, I was trying to accomplish this via asound.conf:
something like:
pcm.foo {
   type multi
   <map soundcard>
   <map headset>
}
pcm.bar {
   type route
   slave.pcm "bar"
   <map channels card out -> hs in>
   <map channels card in -> hs out>
}

hope the idea is understandable

http://www.alsa-project.org/alsa-doc/alsa-lib/pcm_plugins.html#pcm_plugins_route

but I guess this won't work

C hacking? ;) well, if there is really no other way, i could
try it. Are there some docs around to dig in or just the btsco
sources?

greetings
