I tried what you suggested, but it didn't solve my problem.
I have Creative Inspire T3100 speakers. I can only get sound through my headphones.
One of my electrical engineer friends told me to try to kill some Windows option called Digital Line Detect:
"So you might be able to do something about this. If you have some feature/setting/Windows-7-option about Digital Line Detection enabled, try to disable it. What's probably happened is that the headphones were damaged and ran a bit too much current through the socket, changing the impedance of the socket, and making it "seem" to the computer as if something was plugged in. With Digital Line Detection turned off, you can probably specify speaker or headphone output respectively."
My Google searches haven't given me any hits relating digital line detection to sound.
He also thought that I was talking about on-board sound, not my Creative Inspire T3100 speakers. After I told him that the issue is with my speakers, he believes that this is a physical problem.
What other things should I explore?
