Comment # 1 on bug 991612 from Stakanov Schufter

I can confirm now that the audio profile is a generalized problem of bluez. 
I did a new install. 
I tried with new hardware (Pioneer BT Headset SE-CL761BT-K).
Again the choice drops always to the hdp/hsp profile. 
If you can make it to the A2DP by chance, avoiding more then one user (like
Win98 - wow, we are making progress) then the system will have sound
interruptions, no bass, and the setting will not be recalled once set in a
future session. 
As stated, even with the A2DP the sound quality is miserable. 
There does not seem to be a way to durably force the system to recall a BT
audio profile once more than one user is logged in.
