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.

I updated topic/hda-mst branch with these patches. But the patch 4 needs more fixes, as suggested in another mail.
Thanks. Do I need to resend all the patches? Or just patch 4 and patch 5?
Only 4 (and 5 if needed) should suffice.
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?
Yes, I have all the patches in my local branch. We tested the patches before. But since a lot of code in mainline is changed, I need rebase the patches. Some patches are conflicted with the jack changes you made. Some also fix some unsol event issues, which seems you have made a lot of changes on it currently.
Well, it doesn't matter how old it is, but I need the branch to test whether MST really works at all. Could you publish your git tree and your old branch that worked? You can use github or whatever.
OK. I will submit the patches to github and let you know the branch later.
Best Regards, Libin
