I have installed the Audio Mixer (Alsa Mixer) on my desktop as I could not control the audio volume in MythTV.
At first, the Master Volume moved the sound volume up and down. Then I added "Headphones" from Select Controls. After that, I have no sound in any application. VLC plays but no sound. MythTV shows tv picture but no sound. I have rebooted to see if that would correct itself. No I have not Muted the sound and missed the little X through the loudspeaker icon.
Audio Mixer title bar reads in full: Audio Mixer - HDA NVidia (Alsa mixer).
Sound card (pull down menu reads): HDA Nvidia (Alsa mixer)
USB Device 0x46d:0x807 (Alsa Mixer)
Playback: Built-in Audio Analog Stereo (PulseAudio Mixer)
next come capture devices. Is that relevant? See screenshot if relevant.
Moving the Audio Mixer applet to the desktop brought up a warning about "not executable" and trusted. I clicked Make Executable or some such.
And each time I call (run) the Mixer Applet, the Master Volume's loudspeaker icon is set to Mute (x through it).
I find a related idea at: https://bbs.archlinux.org/viewtopic.php?id=139723
And this guy had to compile the Alsa driver - http://www.debianuserforums.org/view...hp?f=55&t=1969
The following URL had a temporary fix.
Run this line:
for i in $(amixer |grep -o \'.*\'); do amixer set $i unmute; done
I may be goofy wrong about this but this bug seems to have fubar'd my panel icon for Thunderbird. It won't launch.
Anyone know what has happened here?
