hey, i have an imac g5 (pre-built in isight) and at times i'll notice that music sounds weird and i'll check the sound preferences and the speakers will be unbalances even tho i did not set them that way. has anyone else experienced this/know how to keep it from doing this? its not a major problem, it just gets annoying. p.s. i did search the entire forum for this subject and nothing came up so if this has been posted a million times before i apologize for wasting a few minutes of your life.
