any way to output sterio through all channels?

[tmaxxthomson]

ive got a logitech Z-5500 sound system and an asus xonar D2X (or something) its pci-e anyways. and its annoying listening to music loud but only using the 4 coner speakers. is there any way to put it out through the center channel aswell? would be good to take advantage of them all for maximum volume!

Stereo music isn't usually recorded with a centre channel in mind, so I don't think it's possible.
