Maybe some power saving feature in the hda driver?

My mobo sound doesn't have any problems, it's just hdmi, anyway it seems like 0 is in my kernel config, but I also tried

snd_hda_intel power_save=0 but no luck.

I also tried several other things but none worked, I did get rid of acpi_cpufreq.

snd_hda_intel position_fix=1 and 2, and after noticing my mobo sound wasn't using msi but radeon was I disabled that, but it didn't help.

Also tried single_cmd=1, but got no sound at all with that (mobo sound still worked).

Attaching dmesg.
