So I added

pcm.bluetooth {
   type bluetooth
   device 00:1A:45:14:EE:D7
}

to .asoundrc and if I try to play something with aplay, I am told that

  Playing WAVE '/usr/share/twinkle/ringback.wav' : Unsigned 8 bit,
  Rate 8287 Hz, Mono aplay: set_params:918: Sample format non
  available

Trying to use the device with twinkle, the programme starts up
taking ages trying to connect (http://bugs.debian.org/475962) and
eventually just says that it cannot access the speaker/microphone.
When twinkle tries to talk to the headset, the bluetooth LED starts
to blink, the headset makes the
noise it makes when a connection is established, and after a while,
twinkle tells me

  snd_pcm_hw_params failed: Invalid argument

and then

  snd_pcm_hw_params failed: Input/output error

The bluetooth LED continues blinking and the headset will not make
the disconnection sound until I turn bluetooth off. Once I turn it
back on, the headset disconnects, and the cycle repeats.

I am using 2.6.27-rc4 and bluez-utils 3.36-1.

Any ideas what may be wrong?
