[pulseaudio-discuss] bluetooth source not created

[Marco Trapanese]

I'm running pulseaudio8 and bluez5 in a buildroot environment (RPi3). 
When I connect the smartphone I can successfully pair and authorize 
UUIDs for Advanced Audio Distribution and for A/V Remote Control.

It doesn't ask for Audio Source.
In fact pactl list sources doesn't show the bluetooth source, thus I 
cannot loopback with the local sink.

The daemon is started in this way:

pulseaudio --system --daemonize --disallow-exit 
--disallow-module-loading --exit-idle-time=-1 --disable-shm --fail

I attach the system.pa file.
Please feel free to ask me any other information you will need to help 
me to understand what I'm missing.

Another question: what's the difference between modules 
bluetooth-discovery and bluez5-discovery?

Best regards
Marco
