[pulseaudio-discuss] [PATCH v4 5/8] 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 in that case.
