2 rear speakers on inspire 5.1 wont play

[Durgess]

after getting a SB audigy plat i decided to pick up some 5.1 speakers today, the inspire 5.1 5200. after much tweaking i cant get the rear 2 speakers to work at all. ive tested them out in the surround mixer and they just wont play. i've checked the wiring and everything seems to be in order. am i doing something wrong, or are these speakers defective?

Welcome to TechSpot
What happens when you connect those speakers to the front, do they play then?

they play. so the speakers work ok. thats a relief. still cant get the back 2 to play, however.

What motherboard are you using?

I just bought some Logitech Z640 5.1 speakers and had to download NVSWAP, which switches your Mic In, Line In, Spkr Out, etc. to be used as a Front L/R, Rear L/R, etc.

Then I had to download the updated Nforce2 drivers which included a utility called NVMixer which lets you tweak your speaker's settings, EQ, etc.

After that everything worked fine. (I had the same problem beforehand).
