Dang Justin...No Radio Shack part #? You're slipping Anyway I was confused about the mono y-adapter because of the speaker wire mod.... Doh! Anyway, if I try this and the sound is fine am I then to believe that it is absolutely NOT the speakers (sats or sub)? and that it must be a mobo problem... I have had this ASUS alittle over a year now and I have not updated the BIOS. Although I'm not sure if that would have any bearing on a problem such as this? Wouldn't it be more of a PCI slot problem, rather than the entire board?
