bluetooth: audio takes a few seconds to start

[tmigone]

Description

• Audio takes a few seconds to start, not playing.
• bluetooth disconnects
• bluetooth automatically reconnects and audio only starts to play

Affected devices This is likely related to headset_audio_gateway profiles getting in the way, or at least I haven't seen this problem with a2dp only devices.

Steps to reproduce It happens occasionally when starting playback, specially after at least 5 seconds of not streaming audio (5 seconds is the default time where PA sources go from RUNNING to IDLE).
