Only 2 speakers work

Question

for christmas i put in a new soundcard and it works fine, but now itunes only uses 2 speakers in my 5.1 surround sound. I know the speakers are working because when i do the creative speaker test i can hear each speaker working. But in itunes it only uses the front left/right speaker and the subwoofer. I'm pretty sure that its just a setting but i don't know how to fix it. Any advice would be much apreciated.

Answer 1

I'm not aware of a setting within iTunes, but I had a similiar problem. I didn't want "5.1" sound out of my stereo music, but I did want sound to come out of each speaker while playing music.
On my particular set of speakers, there is a switch that allows real 5.1 sound (like for games and dvd's), and then another position which will pump a 2.1 signal through all speakers. That worked for me, check your speakers and the control unit of your speakers for a similiar switch.
