My sound is all screwed up; I don’t know if it’s because of the speakers or because of the settings. However, when I play a video file, the music plays perfectly (most of the time), but the speech tends to be really, really quiet and sort of robotic or warped-sounding.
Didn’t work. It might be a speaker problem then. I remember that once the sound went all weird, but I turned the spaker off and then turned it back on and it was fixed. This was a while ago, though.
