Expected behavior: sound working over HDMI. Real behavior: no sound at all. Solution: I installed "GRUB Customizer" and put the following command in the kernel parameter (which I found after a lot of research): "quiet splash radeon.audio = 1" This needs to be resolved urgently, it can alienate novice users.
