i have faced this problem before, the problem comes when xfce4-mixer ,xfce4-volumed and pulseaudio are installed at the same time.
Xfce4-mixer doesnt need pulseaudio at all because of ALSA, you need to remove it with: "sudo apt-get remove pulseaudio pulseaudio-alsa" -- You received this bug notification because you are a member of Ubuntu Touch seeded 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.
