sound: clear the value on level_bar when stream is empty
We met an Input Device level_bar display issue on a machine which has
no internal mic. At first there is no external mic plugged, so the
Input Device list is empty and level_bar is gray color, after we plug
an external mic, the level_bar has red color ripples, then we unplug
the external mic, the Input Device list changes to empty and we
expect the level_bar changes back to gray color, but some bars are
still red color.
Here clear the self->value to 0 if the stream is empty, then the
level_bar will change back to gray color when Input/Output device
list is empty.
