[alsa-devel] about UCM on bluetooth headset

Hi Liam,

In alsa-libs:include/use-case.h, there are below lines:

* a conversation etc. The device describes the physical audio capture and playback * hardware i.e. headphones, phone handset, bluetooth headset, etc.

I'm not quite clear about how to set a use case for bluetooth headset. According to my understanding, bluetooth doesn't fall into the category of ALSA, therefore there's no such direct devices for it.

Could you shed some lights on this? What's the best practises to use UCM with bluetooth?
