built in sound not working!

[underdawg]

The last time I plugged in my Apogee One USB interface (like I have done many times before) and then unplugged, I noticed that I get no sound. In Preferences, nothing shows up under output/input devices. I also get that weird grayed out sort of icon when I press the volume keys on my keyboard.

Sound works fine when the interface is plugged in, but is there any way to "reset" this?

Try to see if you Reset Your Pram (hold down the keys for 3 bongs before releasing the keys). It might help.
