> changing "switch" from "mute" to "on" under [Element PCM] in /usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common (see below) did have an effect -- pressing the "mute" button now only mutes Master and Headphone (not PCM anymore), pressing it again only unmutes Master. Changing the same for [Element Headphone] in /usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf fixes the Headphone mixer behaviour for me, too.

[Element PCM]
 #switch = mute
 switch = on

it is because the master switch mute/unmute the mixer output to all output pins but pcm playback switch mute/unmute the audio output into this mixer

the latest alsa driver always set unmute this switch and set to 0dB instead of let user to control
