I moved. And when I plugged my speakers back in my computer, they didn't work. I don't even get a ding when I change volume controls. I think it may be a problem with my computer, as I tried a different pair of speakers, and they don't work either. I have checked my volume control panel, and nothing is muted. yes, it is plugged into the back. windows has determined that my drivers are up to date. i just got this hp computer in february, and i have windows vista. i use my commputer mostly to listen to music. please help.
