Nach dem Einbau einer neuen Grafikkarte der Radeon RX Serie, ging das Bild zwar out of the Box aber dem HDMI Anschluß war kein Sound zu entlocken.
Das erste grep von amdgpu auf /var/log/messages brachte mal fogendes:

Und jetzt der sound
Um die Soundausgabe unter HDMI zu aktivieren muß beim opensource AMDGPU Driver das DC akivieren.
Damit amdgpu den DC Mode verwendet gehört noch eine Kernelparameter via grub mitgegeben, und zwar amdgpu.dc=1
cat /etc/default.grub ... GRUB_CMDLINE_LINUX_DEFAULT="amdgpu.dc=1 quiet" ...
Dann klappt auch der Sound, es muß halt noch das richtige Device in PulseAudio augewählt werden (zb mit pavucontrol), in KDE kann man das richtige Device auch in den systemeinstellungen -> Multimedia -> Einrichten der Audio-Hardware einstellen.
