Hi. I have a Motorola H300 headset that works reasonably well with
headsetd (including using it with Twinkle, a SIP softphone). I've now
attempted to get it running with the bluez audio service - I'm using
bluez-utils 3.18 in Ubuntu Gutsy.

Playing sounds using "mplayer -ao alsa:device=bluetooth file.mp3" works
well with the bluez method, but when I start Twinkle, I don't get any
sound and Twinkle pops up a dialog saying "Unable to access speaker.
Unable to access microphone." When Twinkle starts, the audio
service spits out these messages:

Does anyone know what the problem could be? Could it have something to
do with trying to use the same alsa device for both input and output?

Thanks in advance,

Johan
