Using Mint 17 + MATE here. My bluetooth headset (Plantronics Backbeat Go2) is connected just fine with my system, but there are several manual steps I have to take to make this work that I would very much like to have automated:

  1. After every reboot I have to run pactl load-module module-bluetooth-discover in the terminal to get the device to connect at all. I tried putting this in a shell script to run on start up, but no dice :(
  2. My headset connects automatically with no issues, but it always defaults to Telephony Duplex or even Off instead of A2DP; I've tried and failed with several different strategies to force A2DP :(
  3. Force the BT headset to be the default output device. Tried several strategies here, too... unfortunately every time I connect the headset the index from pacmd seems to change, so I can't force a default in the PA conf file set-default-sink that way. And using the listed name doesn't seem to work either - if the headset is not present, it switches to the speakers and doesn't switch back if the headset connects :(

Thanks for any advice you might have on resolving these issues!

  • I think the solution is something with udev, but im not sure how it should be done. – hschou Jun 2 '17 at 9:29

The first problem occurs because Pulse Audio unloads the bluetooth module after startup, so even if you put it in your startup script, it still gets unloaded a few seconds later.

  • Solution A

    Just add a startup delay in your script, something like:

    sleep 10 && pactl load-module module-bluetooth-discover
  • Solution B (recommended)

    1. Disable the bluetooth/Pulse Audio plugin.
    2. Right click your bluetooth icon, select Plugins, then uncheck the Pulse Audio plugin.
    3. Restart.

Sorry, but I don't have a solution for your remaining two issues.

Re #3, my solution is this:

  • Add a unified device (simultaneous output to all devices) that merges all others
  • Use that as the default output device
  • Keep all other physical outputs muted except the BT headset

The benefit is that all programs can send output to that regardless of whether the BT headset is connected or not. Then, once the headset connects, it starts receiving the sound.

If you do that then you should also set flat-volumes = no to /etc/pulse/daemon.conf and only control the unified output with your volume control keys.
