Ubuntu – Blueman audio profile w/ headset: HSP/HFP no quality playback – A2DP no mic

• This is a known bug in bluez with the new Broadcom BCM20702A0 series adapters; yours is one of those. (see bug report)
• The bug is rated "high", but it has not yet been fixed. You may want to add yourself to the list of people affected by the bug, and maybe post a message asking if there is any timeline on a fix.

Other possible solutions:

• Edit /etc/bluetooth/audio.conf and under [General], add the line Enable=Socket. Restart blueoothd with sudo rfkill block bluetooth && sudo rfkill unblock bluetooth and see if it helps.

A solution seems to be worked on (I hope), I've been following this bug report on Launchpad, but hasn't been very active.

If a solution comes about I'll update my answer.
