Public bug reported: Video works fine, but no audio via HDMI - devices show up properly in 'aplay -l' but do not show up at all in pavucontrol or under the normal audio devices. Testing with wav files to the devices yields no audio either. Headphones and all other audio (including bluetooth) work fine.
