Since unplugging all my system and back in again i cant get sound working properly :/ im using the asus board onboard audio, got them all plugged in, there colour coded which im sure i had them all right before and it worked but now im having lots of problems, Center, sub and rear all work fine, but front speakers dont want to work at all :/ had the speaker setup on 5.1 and nothing, only way i can get them to play anything is by plugging them into side speakers port and set audio to 7.1 :/ which is annoying as now things like website flash videos etc i cant get any audio now, any ideas please?
