> 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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1254884 Title: Pulseaudio: incoherent muting of GStreamer channels (mutes master, headphone and speaker, but unmutes only master) To manage notifications about this bug go to: https://bugs.launchpad.net/pulseaudio/+bug/1254884/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
