Comment 0 for bug 24090

Using the Gnome mixer applet to control the system volume, I dragged the slider
all the way down to the bottom; the little X came up on the applet icon, and
Mute was checked in the right-click menu, so I suppose it thought it was now
muted. However, it wasn't; sound still came out of the speakers at very low
volume. I assume this is a bug in the applet. Setting "Mute" manually at
non-minimum volume mutes the sound, but apparently, when you set the volume to
minimum, it thinks it's muted when it really isn't.

Sorry I couldn't figure out the correct package to mark this bug under.
