[Deprecated] [TESTING] Bluetooth audio streaming (A2DP)

I tried the new release yesterday and am able to pair my Pi 3 with my phone.
Once starting to stream from my phone to OSMC I hear the music but it starts immediately to stutter, and sounds quicker than the original music is. Sometimes it simply stops until I stop the playback on my phone and start it again (with the same result).
I have no issues with other bluetooth devices (bluetooth speaker, car audio,…) when streaming from my phone.
The app I’m streaming from is Amazon Prime Music on Android. Streaming from another app (like YouTube) seems to work, but I guess there are different codecs/bitrates involved causing the issue.

I checked the kodi.log in debug but it does not show anything. But journalctl contains the appended output.
The lines at the end (“frame assembly failed”) repeat quite often so I took only some of them.

Hope that helps finding the issue.
Thanks again for the great support!
