Well, I was playing Oblivion the other day when it suddenly crashed and I got the BSOD. So, I restarted and realized that the sound no longer worked. I used Everest to find out that my sound card is "Realtek HD Audio output". I've tried installing two new drivers, Device Manager shows no problems ( and didn't prior to the new drivers being installed ). I see no reason why the speaker system itself would be damaged seeing as it worked perfectly prior to the crash, and then not at all after the crash. Volume is turned all the way up, it's not muted, all cables are intact and properly connected. I think I've said all I can say about the problem, and I sincerely hope you guys can help me out with this.
