There is a broken udev rule https://bugzilla.opensuse.org/show_bug.cgi?id=1179363#c7 Does the rule fix work on the Macs?

karlmistelberger you rocks! The changes Takashi Iwai proposed are also working whether or not the startup chime is muted on the UEFI and /etc/alsa/state-daemon.conf exists or not.
I'll reply on the bug report that both fixes are working

Code:

root@raiatea:/home/matt # systemctl list-dependencies sound.target
sound.target
● ├─alsa-restore.service
● ├─alsa-state.service
● └─sound-extra.service
root@raiatea:/home/matt # systemctl status --full alsa-restore.service

Host erlangen was unaffected by the bug so far. However upgrading to TW-20201205 changed that. Fixing the broken udev rule solved the problem.

Yep I saw that on my testing machine (the i5 MBP) after updating to 20201205 snapshot and fixing too the broken udev rule made the trick

Yup saw it this morning.

As per comment #11 from Takashi, I haven't any /etc/udev/rules.d/sound.rules and haven't tested Takashi's alsa-utils package as I didn't encountered the error you had and described in your bug report.

Things are working as expected only by changing card* to controlC* in /usr/lib/udev/rules.d/99-systemd.conf

2 devices were created for each sound card. Deleted the original line, added the new line and checked with Environment=SYSTEMD_LOG_LEVEL=debug. Several rules apply:
