Hi, I seem to have same problem with bluetooth headset Plantronics Backbeat pro2: A2DP works fine, media keys work. But when switching to HSF/HFP, no playback and no audio from mic. Headset seems to switch the mode (something in the Noice cancellation audibly changes) when switching between A2DP and HSP/HFP profile; on occasions the headset "reboots" when changing mode as mentioned in the previous comment.
In https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1768625/comments/3 it was suggested this could be due to missing Headset profile, but on this device both Headset and Handsfree profile are available.
