whenever im listening to music my speakers click sometimes. they are altec lansing 5.1 speakers (cant remember the exact model). speakers are a few years old, but have only been in use for a few months. my brother ordered these when he got a new comp to go to college but then decided to get a better comp sound system so these have been sitting around until we finally got a new comp. i bleive my dad might have gotten just the base sound card with the new comp so could this be the problem - base sound card + upgraded speakers?
