How can I enable sound via HDMI with openSUSE Tumbleweed at an Raspi4? This bug report says, that it should be possible: https://bugzilla.opensuse.org/show_bug.cgi?id=1177169
This issue is fixed since month on Tumbleweed
I have to use a kernel > 5.10, so Leap 15.3 is not ok, I changed to tumbleweed KDE (X11 does start only with root via startx, but I think this is the smaller problem.)
I use hdmi0, my extraconfig.txt is:
there is no extraconfig.txt on my system. I set it up on Friday und running fine with only described steps. I would remove/shift this file, so it isn't used at all.

hdmi_drive=2 hdmi_group=1 hdmi_mode=16
hdmi_force_edid_audio=1
At Tumbleweed HDMI sound works out of the box. You need only to go e.g. at KDE to the loudspeaker icon and switch there to Digital Output (HDMI or S/PDIF). Afterwords on my ASUS MB16A I can listen the Sound quite well. In worst Case test all possible outputs and test it. Please consider, that audio system is changed from ALSA (JACK) to pulseaudio!
