Bluetooth headset in Ubuntu Gnome

One of the most difficult things about moving to Ubuntu Gnome so far has been my Bluetooth headset of all things. It paired and worked brilliantly right out of box, but after a reboot the quality was woeful. Turns out the audio profile had changed to HSP\HFP - Headset Head Unit when I wanted it to be A2DP Sink - High fidelity playback

This site appears to have fixed my issue - I used the second workaround and also chmod'd the file to gdm:gdm before rebooting https://wiki.debian.org/BluetoothUser/a2dp#Refused_to_switch_profile_to_a2dp_sink:_Not_connected
