Unfortunately it doesn't in my environment. :-(

Hrm. I don't know that I have to or know how to do this with my
headset. Can you elaborate?

When I use sox to provide the same kind of input, I get no luck:
$ sox /mnt/mp3/bad_mouth.wav -c 1 -b 8 -r 8k -t wav - | aplay -D bluetoothfoo
Playing WAVE 'stdin' : Unsigned 8 bit, Rate 8000 Hz, Mono
I still get nothing except the headset beeps when the stream starts and
then ends. FWIW, my alsa configuration for bluetoothfoo:
pcm.bluetoothraw {
type bluetooth
device 00:1A:45:1B:19:89
#profile "auto" #optional, supported profiles are: auto, hifi and
voice
#profile "voice" #optional, supported profiles are: auto, hifi and
voice
}
pcm.bluetoothfoo {
type plug
slave {
pcm bluetoothraw
}
}
Trying to use bluetoothraw directly doesn't work either:
$ sox /mnt/mp3/bad_mouth.wav -c 1 -b 8 -r 8k -t wav - | aplay -D bluetoothraw
Playing WAVE 'stdin' : Unsigned 8 bit, Rate 8000 Hz, Mono

Just for contrast, here's mine:

Interestingly enough, both are Broadcom dongles.
