I'm trying to set up A2DP+HFP profiles in an embedded board. Goal is to use pulseaudio 12.2, ofono 1.18, and bluez 5.41 in order to connect to a mobile phone and use A2DP, HFP profiles automatically, whenever necessary. I did lots and lots of things to update the versions and configure the daemons. Right now I can see that HFP profile is available when connected.
A2DP works perfectly and I am able to stream music from phone to embedded board. When I get a call, I can answer it with Bluetooth and it looks that HFP is the active profile whilst I'm in the call. The weird thing is that there is no audio from the embedded board (HDMI monitor connected to it).
The following will give you how it looks like. When I'm streaming music from phone via A2DP, I get following sources and sinks:
pactl list short sinks
0 alsa_output.hw_1_0 module-alsa-sink.c s16le 2ch 48000Hz SUSPENDED

Whenever I'm in the call (using HFP), I get following sources and sinks:
pactl list short sources

This is quite weird since sink changes from my HDMI monitor to the bluetooth device itself whenever I am in the call. Please find my /etc/pulse/default.pa below:

Any help is greately appreciated. Thanks in advance.
