you might want to set cards_limit to something higher, as some systems have multiple hdmi outputs, 2 might not be enough. i think the default is 8.

@bunder: i have change to 8 - its not better.

I have deactivate the sound in BIOS for test. In Linux - Mint i get sound. I got there hdmi in more modules.

Code:
user@auchegal ~ $ lsmod | grep snd
snd_hda_codec_realtek 86016 1
snd_hda_codec_hdmi 45056 1
snd_hda_codec_generic 73728 1 snd_hda_codec_realtek
snd_hda_intel 36864 4

    snd_hda_codec_hdmi,snd_hda_codec_generic,snd_seq_device,snd_hda_codec_realtek,snd_pcm
soundcore 16384 1 snd

I try to load the module manually but i got an error:
localhost /home/fridolin # modprobe snd_hda_codec_hdmi
modprobe: FATAL: Module snd_hda_codec_hdmi not found in directory /lib/modules/4.14.8-gentoo-r1

Wrapped a long line to make the forum layout behave, and added code tags to the second half of the post to make the terminal output easier for the eyes.Chiitoo
