I recently built my own PC and everything is perfect except no sound comes out from my speakers after connecting it to the motherboard (it has integrated audio). Strange thing is, when I connect the speakers to the front audio ports (for headphones), it works, but the back ports don't.
I'm pretty sure that it is something in Windows that's isn't working, but I have installed the drivers that came with my DFI motherboard (called C-Media) and Windows recognizes it, but still no sound.
However, there is one "Unknown Device" in the Device Manager, but I don't know what it is.
Could it be this? Or is my motherboard broken?
Thanks a lot for your help.
