Dell Inspiron 660 and the SkullCandy SLYR headset

Hi,

So today, I received my Dell Inspiron 660. I immediately went to plug my microphone in after set up. The speaks pick up sound on the microphone slot, but I hear no sound, and cannot make any sound. Then, the headset icon was next. When I plugged it into the headset icon, I could hear noise, but the sound was not transmitting again.

Later, I tried the back, and I could hear sound on the first port, but couldn't talk. Then, the second and third ports didn't do anything! I am wondering if anyone can help me. Please reply as soon as possible. Thanks!
