1.2.13 will lead to mute of speakers and headphone jack on MTL laptop Lenovo Youga Pro 7 14IMH9
Changing version from 1.2.12 to 1.2.13 will lead to not working sound during plug/unplug of the head phone jack or mute during reboot on Arch install. Other ppl with similar laptops have reported same problem. On my version codec is ALC287 with bass speaker output. I can unmute speaker or headphones trough alsamixer, but plugin headphone and the unplugin will lead to both mute. Sometimes reboot will lead to same problem and I have to operate channels by hand again. Similar problems:

edit: reading more seems like problem is with the new HDMI macro, because other report problems with HDMI output.
it is fixed with:

@perexg Hi! What's the status of this bug? alsa-ucm-conf will be removed from Debian on March 9th if we don't fix it before that date (see Bug#1092257 and the autoremoval notice in the tracker). If this was indeed fixed with #463 and https://github.com/alsa-project/alsa-ucm-conf/commit/6397c663d7086b87ca5cbba323ea3dcd0ecd3200, could the fixes be released so we can update? Thanks!
It's fixed in 11b028a9a01e47fc9b48e4a566803752011902e2 (the 6397c663d7086b87ca5cbba323ea3dcd0ecd3200 should be picked too) . Just apply those two patches to Debian package. I will do new ALSA release probably next month. Other distros pick fixes faster.
Sorry, I somehow managed to be unaware of this one! Will upload to Debian rsn.
