[pulseaudio-discuss] [PATCH v5 5/7] bluetooth: Auto recover if profile is 'off'

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.von.dentz at intel.com>

This means something went wrong, which in case of ofono backend it is
probably due to the profile not connecting immediately, but it can be
safely restored in that case the transport is playing which means the
profile has recovered connectivity.
