--- Comment #3 from Tanu Kaskinen <tanuk at iki.fi> ---
Ok, then I guess xfce4-volumed is accessing alsa directly, instead of doing the
muting through pulseaudio.

Explanation for the inconsistency between muting and unmuting: xfce4-volumed
sets the Master switch to muted. PulseAudio notices that something happened in
the alsa mixer, and sees that one of the switches is muted, so PulseAudio
concludes that the device is muted and sets the internal device state to mute.
While setting the internal state, pulseaudio also mutes the rest of the
switches marked as "switch = mute", including PCM. When xfce4-volumed unmutes
the Master switch, PulseAudio again notices that something happened, but since
the PCM switch is still muted, PulseAudio concludes that the device is still
muted and does nothing.

xfce4-volumed should be changed to talk to pulseaudio instead of accessing the
alsa mixer directly.
