Hello everybody,
I would like to send audio messages via bluetooth to a Jabra speaker.
I’ve successfully configured the bluetooth IoT card (from Talon Communications) and the pulse server so I after pairing the bt device I can see the Audio Sink/Source exposed:

But when I try to send a simple audio wav I get this error:

If I undestand well the schematics the 4 PCM lines are connected to the IOT slot 0, where I plugged the IoT card, but seems that there is something wrong in my mangoh green+wp7702 because in dmesg I see lot of error regarding PCM routing:

Seem that I missed some hardware settings or modem command? Any help?
thanks!
