Hello. I just installed LMDE XFCE 201214 on my pc. Whenever I want to mute the sound I just press my mute/unmute button on my keyboard and sure enough it mutes the sound.
But Unmuting is not so easy. Pressing the mute/unmute button on the keyboard does not unmute the speakers. I have to instead left-click on the mixer icon on my panel and then select-controls/ master/ click to unmute the speaker. My Mixer: Sound Card: is set to Playback: Internal Audio Analog Stereo (PulseAudio Mixer)
I've tried adding application shortcuts to my keyboard, but this changes nothing. Any help would be appreciated.
I found out I have the same problem. Seems my keyboard mutes and unmutes Master correctly. But it doesn't unmute PulseAudio. Channel and Mute symbol react in Volume Control but with no effect. Standard is ALSA Mixer. Do I have to remove ALSA or OSS?
For "hotkeys" you have to know keyboard type and key code. Maybe then you could edit/create a def file in /usr/share/hotkeys/
I haven't tried out Multimedia Systems Selector (gstreamer-properties). Maybe it helps to specify the output ...
According to ubuntu forum posts, Banshee, the multimedia program that comes with Mono, does not work too well with gnome3. There are plenty of reports about freezes and sound going mute. Removing mono completely (also removes Tomboy notes, Giver and many libraries) seems to have solved my sound problems. The system does not go mute anymore (so far).
