I'd use google but I don't even know what to look for, so maybe someone here knows what the problem could be.
I use a laptop, and the sound has been working just fine all day while the external speakers were plugged in.
But if I unplug them, suddenly the sound is gone. I don't know why that is, I've never had this problem before and I certainly haven't been messing with the setup.
Why won't my laptop play any sound on it's internal speakers?! Any idea what I could do in this case?
