alsa-project/alsa-ucm-conf issue #472 was edited from phush0:

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.
