Sound Abrubtly Cuts Off

[hershewed]

Ok, so the sound has been suddenly cutting off on my laptop, and the only thing that I know that fixes it is pressing the power button, putting it to sleep, and turning it on again. I know it could have something to do with drivers, but is there anything else that may or may not cause this? If so, how does one fix it?
