[regression] Bluetooth audio devices are not connected

[Takkat]

Binary package hint: bluez

A known Bluetooth headset is not connected any more in Ubuntu 10.04 LTS. Security and recommended Ubuntu updates were installed last on Dec 22 2010. Before that the device worked as it should.

The device can be browsed using 'sdptool browse MAC' but does not show up in in the bluetooth-applet drop down menu and is not shown in bold letters from the properties menu. Scanning for new devices also does not see the device thus re-pairing is not possible. Connecting the device as audio sink to PulseAudio fails (device not listed).

By running 10.10 in VirtualBox on the same hardware the headset was connected as usual, proofing that there is no hardware defect.

As a wokaround reconfiguring a device by removing the device and re-setup makes it operate again as usual.
