yeah, my windows XP home edition dosen't have one. In my list of sound devices, next to Multimedia Audio Controller is a big yellow question mark, I try to install it but it wont work, it says it cant find it, and if it comes with an installation CD or floppy install it. So ive got no sound! problem is, though, I dont know all that motherboard or model stuff is, umm, its a home edition, its white, its from LG, umm studioworks, 700s, and thats all I know. Pleasem PLEASE help me, i miss sound!
