os : ubuntu 22.04
VGA : Radeon RX 570 Series

I have sound with mother board sound output.

The HDMI is hooked up with my graphic card which RX 570.

lspci shows that the audio card has been detected.

  • Related: https://askubuntu.com/q/1336087 but you might want to use module-alsa-sink or even module-alsa-card and aplay -l similar to how module-alsa-source and arecord -l are discussed in the linked post ... Also please copy/paste text from terminal and don't add screenshots of text for readability. – Raffa Mar 04 '23 at 11:34

It seems there is a problem with the kernel.

Try to boot with an older one. My PC is running with 5.19.35. Started with 5.14.xx (just any older kernel that was installed) and the HDMI devices were found.
