No sound with Bluetooth headset PulseAudio

[Yaroslav]

Hello,
I am able to successfully pair and connect the headset.
I am able to play audio trough the headset with “a2dp_sink” profile.
But, when I switch to “headset_head_unit” profile, I can’t play nor record audio.

Please help!

P.S.
My setup:
Solid Run HummingBoard EDGE, SOM V1.5(i.MX6)
