Both Rear Speakers Not Working

[Gandalf on Crack]

Anyways, here how it goes. I just put my computer back after a failed upgrade and once I reformated and got all the drivers and whatnot reinstalled I noticed that the sound was....less then adequate, soon enough I noticed my 2 back speakers were not playing any sound from my computer *gasp*. So I checked all the cables to be in the right place, and they were. I checked to see if the speakers broke, and tested it with a walkman, and they all worked fine.....

So, I am on a Turtle Beach Santa Cruz, and I have been enjoying this card thoroughly for the past half year maybe, If anyone has any ideas on issues that could deal to this or if you think it looks like the sound card has had its troubles, I'd like to know...


-Thanks
