[SailfishDevel] Cannot resume playback with Bluetooth headphones

[E.S. Rosenberg]

Hi Anton,
As of late I have also noticed this but haven't had the time to dive into
it (also kind of blamed the headset with which I'm less then happy).
Ssometimes I need to do a manual disconnect/reconnect, phonecall or even a
reboot to get sound output back again.
Sorry I can't be of more assistance beyond confirming you are not "seeing
things".
Regards,
Eli
