PROBLEM: No sound on ASUS ROG Zenith Extreme in 5.6.5

PROBLEM: No sound on ASUS ROG Zenith Extreme since 5.6.5

When I upgraded from 5.6.4 to 5.6.5 I noticed that my sound stopped working.

My motherboard is a first generation "ASUS ROG Zenith Extreme".
(I'm running Ubuntu 18.04 in case that matters.)

I'm pretty sure it comes from stable kernel release commit
7f722d9aa00fde795834840cc84e13a94efb29ed
(git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git) which
notes "commit 3c6fd1f07ed03a04debbb9a9d782205f1ef5e2ab upstream."
("ALSA: hda: Add driver blacklist").

When I comment out 'SND_PCI_QUIRK(0x1043, 0x874f, "ASUS ROG Zenith II /
Strix", 0),' in sound/pci/hda/hda_intel.c my sound works again.

(In case I chose incorrect places to write this mail to I'm sorry. I
tried to follow
https://www.kernel.org/doc/html/latest/admin-guide/reporting-bugs.html
while keeping this report minimal.)


Kind regards
