I noticed that the number of channels muted at once may depend on the
port chosen in pavucontrol's Output Devices tab. In my system, if I
choose "Headphones (plugged in)", muting affects only to ALSA tracks
called Master and Headphone. If I choose another port, muting affects to
Master, Headphone and Speaker.

Title:
  Pulseaudio: incoherent muting of ALSA channels (mutes master,
  headphone and speaker, but unmutes only master)

Status in PulseAudio sound server:
  Unknown
Status in pulseaudio package in Ubuntu:
  Confirmed
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.
