i got a hp pavilion pc from a friend and he wanted me to install a nvidia card and a new sound card. the sound card is an audigy ls and i used the drivers from the cd. i formated it and if i try to use the onboard sound (which is an asus a7n8x) and/or the audigy sound card nothing works past 2.1. i'm using the nforce 2.45's for the mb drivers. if i use hp's recovery disks 5.1 works, but i don't want to use that crap. i just want what i put on there! i also disabled the onboard sound thru the bios. still no proper sound. can someone help me out? thx!
