I can also confirm that using these 4 commands sound works perfectly fine on UX533FTC. It seems that the only last 2 commands are needed to be executed in sequence, but using all 4 commands works fine too (or maybe I can't tell the difference? lol).
hda-verb /dev/snd/hwC0D0 0x20 0x500 0x1b hda-verb /dev/snd/hwC0D0 0x20 0x477 0x4a4b hda-verb /dev/snd/hwC0D0 0x20 0x500 0xf hda-verb /dev/snd/hwC0D0 0x20 0x477 0x74
So in conclusion, if sound still doesn't work for someone, try these:

It's also been historical issue with Asus laptops, when there is no sound after reboot from Windows to Linux. Full shutdown or sleep & wakeup fixes this. Maybe I unintentionally described this in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1850439/comments/148 :)
