OK, long story short, I took the motherboard out of my broken case and put it in a new case. The board is from a compaq presario S4110CL and is an ASUS A7N8X-LA. I changed cases, and now suddenly my sound doesn't work. I haven't hooked up all of the wires yet (because I don't know where they all go) but would this cause the sound not to work? All of the wires go to the front panel so I wouldn't expect that they'd make a difference on the sound from the rear.
Any advice is mucho appreciated.
