Ah, if the pa changes fix the realtime issue they are worthwhile to have even without them fixing hdmi, because currently the realtime issue breaks pa altogether on Bay and Cherrytrail systems. I will start a Fedora pa scratchbuild with these patches added and see if that fixes the need for disabling realtime-scheduling.
As for the kernel-side issue causing hdmi audio out to not work, do any of the kernel devs reading along have an idea where to start with debugging this?
