Package: bluez-alsa
Version: 4.87-2
Severity: normal

--- Please enter the report below this line. ---

Using an LG HBM-235 headset, and a Conwise Technology Co., Ltd. CW6622
bluetooth usb adapter I can pair the device, but get no audio.

Same headset on another system (running still Debian sid), with built-in
bluetooth adapter works.

Pairing (from bluetoothd -nd):

According to that audio should be playing but I hear nothing.
Could be a mixer issue, but I can't set mixer levels using alsamixer:
alsamixer
cannot load mixer controls: Broken pipe

My .asoundrc:
pcm.bluetooth {
  type bluetooth
  device "00:18:6B:E3:AB:03"
  profile "auto"
}
ctl.bluetooth {
    type bluetooth
}

I tried pairing with the device both using KDE's bluetooth applet, and
GNOME's. Pairing goes well (I hear 'connected' in the headset), but no
audio.
On the laptop (with builtin bluetooth adapter) it works if I pair in
gnome, and play music using mplayer.

I use this for mplayer: "-ao alsa:device=bluetooth", and it doesn't complain

Also it appears the device is connected:
$ hcitool con
Connections:
        < ACL 00:18:6B:E3:AB:03 handle 1 state 1 lm MASTER AUTH ENCRYPT

So... is there some mixer setting I'm missing, or is something else
wrong with the audio?
