My computer (recent model Dell z600) has 2 input devices on the front of the computer, 1 has an icon of headphones and the other is a Mic icon.
When I plugin my earphones to the input device that has the headphones, and play some sound I don't hear anything from my earphones (sounds comes from built in speakers).
I know when I plugin a USB headphone set, it switches over to those on but for some reason my earphones are not being picked up.
Is it not compatible?
Note: my earphones look similar to http://www.hdaccessory.com/catalog/reprearphone.jpg
