I've attached a log, of the following... pressing the mute button on my keyboard, so the sound is muted. using the unmute command so the sound should be unmuted. playing a sound in pidgin, getting no sound, because the sound is still muted. hitting the mute button on my keyboard again, which actually unmutes the sound. playing a sound in pidgin, and getting sound I've also attached a screenshot, showing the GUI saying the sound is muted, while alsamixer is saying that it isn't. Note that while unmute doesn't work, setting the volume does. amixer -Dhw:0 set 'Master' 100% Works as expected, for example. I'm also affected by #352732, maybe related.
