I have been using a Soundblaster sound card for a long time and used it for front and rear speakers by means of using two outputs to two amps. I got a Pinnacle capture card and it would not allow me to use the SB sound card for inputting sound. So as I rwas using a ABIT KV7 Motherboard I tried that for inputting the sound and it worked, so took the SB out. The problem Im having now is that I really need the rear speakers to be working but although I have the rear amp and speaker connected to the rear out put socket on the MB no sound is steered there and everything comes out of the front. I have the speakers set to quadraphonic in the settings as before. Anyone got any ideas why Im not getting sound now from the rear speakers?
