Comment # 2 on bug 991612 from Stakanov Schufter

I can confirm this bug is still valid for Leap 42.2 and 42.3

The headset connects, unlike before (42.2) support is not totally broken, it is
however unusable for its purposes, because playing music only and exclusively
with the profile for headset. A2DP is, if chosen, either immediately forgotten
and switched back (no matter(!) were you set it), or it shows A2DP but it plays
the headset profile for communications. 
In order to have any music playing, you have to set the microphone to zero.
Thus, this raises the doubt that even the headset profile is unusable, haven't
yet found an application using it. 

IMO and in my experience, BT audio in leap is still broken completely. The
automatic switching of devices seem to begin to work now, however.
