Bug description:
[Impact]
Whenever I turn on my headphones they'll connect to my computer but
I'm able to hear the input audio from my microphone and low quality
output audio. I have to disconnect the headphones in the bluetooth
devices and reconnect for it to fix the problem.
[Test Case]
0. Set up your Bluetooth headphones with Ubuntu.
1. Turn off the headphones.
2. Turn on the headphones.
3. In Settings>Sound verify they have reconnected in A2DP mode (stereo, high
quality, no microphone support).
[Regression Potential]
Low. Only the headset code path is affected and the fix has already
been released for some time in BlueZ 5.51 onward.
