raspberrypi4 missing HDMI audio sink in wireplumber

Is this now working?  If so we can resolve the issue. 

https://gerrit.automotivelinux.org/gerrit/c/AGL/meta-agl/+/29800 fixes this. the change is in review

thanks for the update. Reassigned to  

The change was abandoned because the it should only apply to rpi4, and that was doing it to for all platforms. It was about the ACP part (second entry list). So that needs to be changed to only apply to rpi4.

But even with that change, audio playback won't work because apparently we can't set the profiles correctly. That's where I got stuck and it needs to be investigated further. I don't know if that really requires code changes or this it just configuration. would take a look at this.

It doesn't make sense to have ACP change in, without actually finding the root cause of missing audio playback. Once the profile issue was addressed we should have also the ACP change for rpi4.

The first entry in the list is just configuration issue, need to try the correct plug.

based on your comment, is there something that needs to be changed in the code?  I see there is a change that was abandoned in gerrit.
