I bought my klipsch 5.1 speakers roughly a year ago, maybe a year and a half ago. Recently I got up one day and sat down at my computer to listen to some music and nothing came out of the speakers or the sub. There was no power outage or anything the night before. I have no clue what to do, I tried hooking up a friends speakers to make sure the sound card was working correctly, and it worked fine. I am really dissappointed if thats really all I got out of dropping $350 on these speakers.
