Many thanks for your information, Luiz!

In /etc/Bluetooth/audio.conf, I shall let audio routed to ALSA by enabling "SCORouting=PCM", right? Is this the only change for BlueZ?

We are investigating. For SCO over PCM, shall we create new ALSA sink and source, or use the original ALSA sink & source?

I want to know when can I routing audio to the "sco-sink" and "sco-source"? 
For A2DP or SCO-over-HCI case,  I can hook "PA_CORE_HOOK_SINK_PUT" and "PA_CORE_HOOK_SOURCE_PUT" and route audio to the new created BT sink & source when a BT headset is connected. 
But for SCO-over-PCM case, the sink & source is set from external and so I don't know when they are ready to move sink inputs or source outputs to them.


Thanks
Amanda
