sudo tee /etc/modprobe.d/snd-hda-intel-fix.conf <<<'options snd-hda-intel probe_mask=1'
That didn't fix it. I found this post, https://bugzilla.kernel.org/show_bug.cgi?id=206813, which seems to suggest that setting CONFIG_SND_HDA_CODEC_HDMI=y might fix the problem, but I don't know where that setting is (sheepish grin).
Here's the output from dmesg | grep -C1 -E 'ALSA|HDA|sof|HDMI|snd[_-]|sound|hda.codec|hda.intel'
