This bug is pretty obnoxious...
So far the only way I've found to get the alsamixer settings to persist without pulseaudio repeatedly undoing it is editing the pulseaudio config files per the arch wiki here:
https://wiki.archlinux.org/index.php/Dell_XPS_13_(9350)
Hissing/Crackling noises when using headphones section
Unfortunately this disabled the internal mic completely though and the changes will get reset when pulseaudio is updated.
