I had the same problem on my laptop.  Post the output of 'cat /proc/asound/cards'  You might have to disable hdmi audo for the snd_hda_intel driver.

If your machine is still usable, then you want to see 'man modinfo' and 'man modprobe.d'. You can also find guidance in the wiki https://wiki.archlinux.org/index.php/Kernel_modules

The install medium does certainly not come with plymouth, which at least seems to be involved here. Are you actually using arch linux?

This is the output of 'cat /proc/asound/cards':
0 [PCH]: HDA-Intel - HDA-Intel PHC
