(In reply to Takashi Iwai from comment #7) I did the easy thing first. Starting with a new Leap 15.6 install, I tried all 8 bitmaps as a command line parameter: snd_hda_intel.probe_mask=,0x101 through ,0x180. There was no difference in the output of aplay -l, inxi -Axx, sudo dmesg | grep shd_hda. The dmesg output all contained: snd_hda_intel 0000:07:00.6: no codecs found! I will proceed to testing of older kernels. I have been advised to limit the trials to those kernels released after 4/13/2021, since that is the date the Ryzen 7 5700G became available.
