I'm afraid we really need to have the VC4 people figure it out - I count do the two reverts that are reported to fix the RPi3 issue, but it looks like the RPi4 pulseaudio issue needs something else. Any chance you could bisect that? Actually, looking at that first report of yours, the RPi4 sound problem apparently happened in the range 9e9fb7655ed5..7c636d4d20f8 and while that range does have a drm merge from Dave Airlie, it _also_ has a sound merge from Takashi and various ARM SoC updates from Arnd. But most (all?) of the changes in that range to the vc4 source code came from the drm tree. And Maxime in particular. I think. Linus
