Following "zypper dup" on either 20200117 or 20200119 (most likely 20200119),
snd_hda_intel is unable to drive output to either soundcard. (HMDI on an AMD
5600 video card, and an X570 "Matisse" motherboard stereo plug interface. Both
worked previous to update.

/var/log/messages shows the following error, upon initializing the cards:

kernel-default 5.4.7.1.1 and 5.4.10.1.1 exhibit the same behavior. Disabling
either card in BIOS does not allow the other to begin working, and
removing/adding them in YAST2 has no effect.
