It seem that those stac9200 in  90-pulseaudio.rules are affected by this
patch

https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/hda/hda_generic.c?id=3abb4f4d0e7aaad0d12004b5057f4486a688752b

The pin complexes of tac9200 codec does not has mute cap
The volume control and playback switch are shared by headphone and speaker

Pcm playback volume / switch of those stac9200 codecs  are changed to line
out playback volume / switch since auto parser move speaker pin/headphone
to spec->line_out_pins when there is no line out
