Bug Description

Streaming of audio files over bluetooth is not possible in Ubuntu 17.10.

Connecting a headphone requires several attempts.
Then the sound settings have to be selected manually
Even then, the sound offered is mono
I tested with a Bose QC35.
There is a sound profile that requires manual selection and offers stereo speakers.
However, while testing left speaker gives reasonable results, testing the right speaker only produces cracking noise.
Playback of music is virtually impossible (the stream is repeatedly interupted by voice anouncements of incoming calls ??? and reconnection attemts)

To eliminate hardware issues I tested under macOS and the sound quality is excellent (even during working in a spread sheet and a word processor in parallel).
=> issues caused by the software stack
