Comment 3 for bug 1691556

Additionally, this issue also appeared along the line with Ubuntu+KDE and apparently was easily resolved, as described in ubuntuforums.org, [link](https://ubuntuforums.org/showthread.php?t=2318966). Quoting another ubuntuforums.org post (also KDE), [link](https://askubuntu.com/questions/763539/bluetooth-speaker-no-sound-in-ubuntu-16-04), "....So far, it seems that things only go wrong when I try to connect in A2DP mode. Until there is a real fix/workaround, I am going to try to remember to always switch to HSP/HSF mode before powering off or disconnecting the speaker.". So, perhaps in the short-term for Ubuntu+Unity a similar workaround could be found, if this is indeed the correct diagnosis, and in the longer-term figure out why connecting in A2DP mode fails (for both KDE and Unity).
