Hello everyone,

first time for me to ask a question here. Hope I am doing everything right.

My problem is that aplay -l doesn't list the hdmi at all. Video via hdmi is working but there is obviously no sound.

I used the ALSA Information Script to provide the information about my system: System Info

Things I have tried so far:

  • Load snd_hda_codec_hdmi manually as it was not loaded
  • Remove nouveau and install nVidia drivers. Result: System doesn't boot properly
  • Create /etc/modprobe.d/intel.conf and insert options as suggested here
  • Attempted to disable IOMMU by passing iommu=off boot option. Suggested here (This was a rather desperate attempt as I don't understand what IOMMU is actually doing.)

So now I am stuck and I greatly appreciate any hint to get the hdmi sound to work.

Thank you so much.
