Thank you for the help,

Is this anyway related to dbus configuration or selected bus (ssystem vs session) ?
>> * Same for HFP, nothing related to bluez_* in pactl or pacmd outputs. Again i can see the audio levels changing in pavucontrol (connected from external machine with PULSE_SERVER) but only one side audio is working which is from device side mic to other end. on the other side (calling phone to device) the levels are changing but seems to be not routed to the default sink (since the levels are not changing in the default sink)

You were right, as per the logs the module-loopback loaded two times,
[pulseaudio] module.c: Loaded "module-loopback" (index: #41; argument: "sink="bluez_sink.CC_C3_EA_0A_15_90" sink_dont_move="true" source_output_properties="media.role=phone"")
[pulseaudio] module.c: Loaded "module-loopback" (index: #42; argument: "source="bluez_source.CC_C3_EA_0A_15_90" source_dont_move="true" sink_input_properties="media.role=phone"").
The audio from default source is channeled to phone but i cant hear any output audio from phone on the board while HFP session, so is there any way to control or verify the the source sink routing during the HFP session.
