Bluetooth headset A2DP works, HSP/HFP not (no sound/no mic)
- by Stefan Armbruster
My Philips SBH9001 headset pairs fine using Ubuntu 12.04. In the audio settings it's properly detected as A2DP device and as HSP/HFP device.
Hardware: Thinkpad X230, Ubuntu 12.04 64bit, Kernel 3.6.0-030600rc3-generic (build from Ubuntu mainline repo), Bluetooth device is USB-Id 0a5c:21e6 from Broadcom, Headset is a Philips SBH9001.
Note: Kernel 3.6 rc3 is used because of a fix for audio on the dockingstation that is not in any previous branches.
Playing audio in A2DP works just fine out of the box, but when switching the headset to HSP/HSP mode there is no sound nor does the microphone work.
When connecting the headset, /var/log/syslog shows:

When switching from A2DP (standard profile) to HSP/HFP:

Any hints how to get HSP/HFP working here?
