Shall we move or cc this discussion on audio driver side to ALSA ML?
Oops I thought I had cc'ed these patches to alsa-devel as well when I
sent them.
I think we also need to decide how to manage PCM devices for DP MST. Now the HD-A driver create a PCM device for each pin, and the substream number is 1 for each PCM. Now with DP MST enabled, each pin can support multiple streams (e.g. 3 on Intel HSW/BDW/SKL).
What hardware feature are available ?
Only three monitors playing different audio streams or
With 1x3 video wall , can the center monitor playback stereo while the left monitor play left channel and right monitor play right channel ?
