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