PipeWire package alsa-card-profiles provides copies of /pulseaudio/alsa-mixer/paths/ configurations at /usr/share/alsa-card-profile/mixer/paths/
$ pamac search -f analog-output.conf.common
/usr/share/alsa-card-profile/mixer/paths/analog-output.conf.common is owned by alsa-card-profiles
/usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common is owned by pulseaudio
so for PipeWire:
sudo nano +136 /usr/share/alsa-card-profile/mixer/paths/analog-output.conf.common
and add
[Element Master]
switch = mute
volume = ignore
