Lots of errors etc in syslog, added some notes on top of the obvious errors.
Kernel keeps spamming syslog with these (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1748565): kernel: [15621.044566] Bluetooth: hci0: last event is not cmd complete (0x0f) Note: this kernel message disappears when and if i get a bluetooth connection that works with AD2P.

Confirmed Bug description: Issue with Sony MDR-1ABT Bluetooth headphones: Once paired, the headphones will be connected automatically whenever they are switched on. However when connected this way, only the HSP/HFP profile will work and trying to change to A2DP in sound settings does nothing. If the headphones are then manually disconnected and reconnected from Bluetooth settings, they will initially use HSP/HFP but then selecting A2DP in sound settings will successfully make them use A2DP.
