Hi,

Please Add following into [General] section of /etc/bluetooth/audio.conf.

Disable=Media
Enable=Socket

And could you test with this setting?

Best regards,

> I try to attach my bluetooth headset (sco) to my laptop using bluedevil and then start arecord. This worked fine with 3.x (from squeeze), but not with the current version from wheezy. I can reproduce this with all bluetooth headsets I got in my hand and with different laptops running debian wheezy. So it seems to be a common problem and not only happen here.
