I fixed it. It was some BIOS settings I did. I loaded the fail-safe settings after I tried to overclock but I didn't think it would actually disable my sound...
I have no idea what happened but my sound is totally gone. Windows tells me I have no audio devices installed, I've tried reinstalling my sound drivers but still nothing. I don't know why it just stopped working I have my speakers plugged in I and I don't think I changed anything.
I seriously have no clue whats wrong. I am using the MSI P6N Diamond's built-in sound card it's a Creative Sound Blaster X-Fi Xtreme.
Did you ever figure this out? I'm using a diamond, too. When overclocking speeds sent my computer into a fever (overheating), i decided to try the restore whatver defaults... only to then have no sound.
