Did you check with "pacmd list-sinks" and "pacmd list-sources" if the
bluetooth sink and source are
available? Did you check if loopback modules get loaded?
If they get loaded, please check if they are loaded correctly. There
must be one module with source
set to your phone and sink set to your default sound device and one
module in the other direction.
You should also see some output of the loopback modules in the
Thanks for the support, things are getting more and more interesting because now,
* A2DP is working fine, but i cant find bluez source or sink in pacmd or pactl outputs,
but same time the loading of module loopback with bluez_source is shown in journalctl logs
module.c: Loaded "module-loopback" (index: #28; argument:
* 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)
Loaded "module-loopback" (index: #30; argument:
card.c: Changed profile of card 1 "bluez_card.CC_C3_EA_0A_15_90" to
some more information regarding the setup,
* Everything is run as root user who is member of audio and pulse groups
* PA daemon is not in system mode
* ofono and bluez is available on dbus system bus but pulseaudio is on dbus session bus
(is this the right way ??)
