> 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 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1254884 Title: Pulseaudio: incoherent muting of GStreamer channels (mutes master, headphone and speaker, but unmutes only master) Status in PulseAudio sound server: Unknown Status in “pulseaudio” package in Ubuntu: Incomplete Status in “xfce4-volumed” package in Ubuntu: Invalid Bug description: with certain audio hardware (those where alsamixer shows separate "headphone" and "speaker" channels) pressing of the mute button on laptop keyboards causes mute of all three channels: master, headphone and speaker. unfortunately, pressing the button again to unmute (or deselecting mute in the xfce audio mixer panel applet) unmutes only the master channel, leaving headphone and speaker muted. there is no other way than opening alsamixer in a terminal (or open mixer controls from the applet) and manually clicking the two remaining channels to unmute.
