Yes, I used the image, provided by Werner. I don't have 5.1 speakers, only 2.1, so I can't check, but H.264 video plays well and shows rkmpp decoder in info. I installed mesa-vulkan-drivers, configured alsa and startup as described in the guide , set KODI_AE_SINK=ALSA in the .desktop file, also installed vop.dts from royk's post. In Kodi settings I set "Allow using DRM PRIME decoder", "Allow hardware acceleration with DRM PRIME" and "Direct To Plane" as per guide.
