alsa bluetooth 16.04 no sound

Asked by MrGrummpy

I have not been able to get sound from my Bluetooth headphones. The Bluetooth software tells me that the USB adapter is paired with the headphones, but still no sound (except the cheery little chimes that indicate pairing).
The sound software lists the headphones, but there is a small red circle with a line through it in front of the headphone's name. This does not allow me to change the profile for the headphones nor does the speaker test work through the headphones.
When I used alsamixer in terminal there is no listing of the headphones even though the Bluetooth interface lists them as paired.
Restarting modules has not solved the problem.
Updating to the latest software has not solved the problem.
Attempting to watch a YouTube video with the headphones paired causes the video to stall. Unpairing the headphones instantly allows the video to continue.
I did get the adapter and headphones to work on both Windows 10 on a borrowed laptop and Windows 7 on my laptop. They don't work using Ubuntu Mate on the same laptop.
I would like to get sound through my headphones.
