The patches are trying to support dynamically binding PCM to pin in HDMI/DP audio.
The pin will not bind to any PCM if there is not monitor connected. When there is a monitor connected to the port (pin), driver will try to find a proper PCM to assign to the port and setup the pin if necessary.

ALSA: hda - hdmi operate spdif based on pcm ALSA: hda - hdmi dynamically bind PCM to pin when monitor hotplug ALSA: hda - hdmi setup pin when monitor hotplug in pcm dynamic assignment mode
I updated topic/hda-mst branch with these patches. But the patch 4 needs more fixes, as suggested in another mail.
Overall, I'd like to know whether MST audio really works in the current state, or not. Do you have *any* git branch where MST audio is supposed to work at all?
I have uploaded the patches to: https://github.com/libinyang/linux.git Branch is mst_virtual_pin_github.
There is still an issue when doing the mst audio playback: The later converter selection for pin will overwrite the previous setting. This is the driver bug, I'm debugging it.

thanks,
