Hello,

I had a bluetooth headset (Nokia HDW-3)  running once (it was in the
times of btsco (I think the whole package was calles bluetooth-alsa). As
I understand bluetooth audio should be its successor. Ok - I tried it
and got nothing. I have the 0.36 Version of bluez installed (compiled
from the debian package).

This is the .asoundrc:

pcm.bluetooth {
   type bluetooth
   device 00:03:89:51:8F:12
   profile "voice"
}

ctl.bluetooth {
   type bluetooth
   device 00:03:89:51:8F:12
   profile "voice"
}

When I connect the headset and try to play sound from mplayer:

mplayer -ao alsa:device=3Dbluetooth <audio file>

I get these entries in syslog:

Jul 21 10:01:29 enterprise hcid[20068]: link_key_request (sba=3D00:03:7A:AA=

Mplayer is frozen and when I try to stop mplayer (Control-C) it reports,
that it was interrupted in ao2_init (the name implies, that it didn't
send anything).

Trying to set the volume by using amixer leeds to a flood of the syslog
with these messages:

Jul 21 09:53:08 enterprise hcid[20068]: Audio API: sending BT_CONTROL_RSP
Jul 21 09:53:08 enterprise hcid[20068]: Audio API: received BT_CONTROL_REQ

Jul 21 09:53:08 enterprise hcid[20068]: Audio API: sending BT_CONTROL_RSP

I really don't know where to look further - any help is appretiated=20

Thanks in advance

Matthias
