Too weird: I have a host with KDE3 and 3 displays running on Slowroll.
If aplay is outputting sound and I click on KMix's mute button, sound
mutes, primary display, on DisplayPort, which is providing the sound,
turns black, and it stays black until aplay finishes and I have LMB
clicked somewhere. This started at least a month ago. Also, KMix's
volume slider is impotent.
