Hello, i do have some old home theatre system around, it is a samsung,is 5+1, and it has 2 cables that i must plug them into my pc to play music . One is red one is white. There are the only jacked connectors. I must plug them into an Asrock fx990 extreme 3 . i have allready headphones, mic in and the line out for the headphones are taken then. i do have some other connection on the mobo, but i really dont know where i must plug those 2 cables from my home theatre.
