Hi All,
With the upgrade to PulseAudio 6.0 last week, my /Bose OE SoundLink/ bluetooth headset no longer connects to the A2DP profile.

The new PulseAudio 6.0 upgrade added a /headset_head_unit: Headset Head Unit (HSP/HFP)/ profile that actually works! Unfortunately, I get a "Refused to switch profile to a2dp_sink: Not connected" when I attempt to switch to the a2dp_sink profile.


It's probably just that - a2dp is not connected. Have you tried to connect it manually?
Run bluetoothctl and enter following commands:
agent on
default-agent
connect aa:bb:cc:dd:ee:ff (address of your device)

After that a2dp should be available again.

Switch pulseaudio profile:

    *$ pacmd set-card-profile 1 a2dp_sink*
    Failed to set card profile to 'a2dp_sink'.


Started pulseaudio in foreground and the interesting logs are here:

    *$ pulseaudio -k && pulseaudio -vvvvv*
    ... (lots of logs)...
    ... (above set-card-profile command executed) ...
    I: [pulseaudio] client.c: Created 6 "UNIX socket client"

Uploaded full logs of pacmd ls and pulseaudio -vvvv: https://gist.github.com/saamalik/7fd15b9826cbede2665c

Anyone have any ideas why A2DP stopped working after PulseAudio 6.0 upgrade?

Thanks,
Saad
