[pulseaudio-discuss] How to use "sco_sink" and "sco_source" in the bluetooth device module?

[Lin, Mengdong]

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?

>Btw, have you tried to hardcode the actual alsa device just to see what happens?
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
