PC doesn't let me hear out of left ear of any headset

[Undead Panda]

Hai, okay so my PC has worked fine with my cheap little Compaq speakers so far. (My PC is about 2 months old).. I had tried to put my iphone earbuds into the PC and it only gave me sound only to my right ear. The left ear hears very little to no sound at all with fuzziness. Also, the left headphone itself (the one not working), got very hot, temperature wise.
Later, today, I bought the Razer Kraken Pros and the same problem happend. Both headphones work perfectly fine on my phone.
- I already made sure it was plugged in tightly and in the right port (the green one)
- I already messed with the sound, making sure both are equal
Please help. D:

Hi,
Is the jack 4 pin http://img.dxcdn.com/productimages/sku_167586_1.jpg
or 3 pin http://s1.flanco.ro/catalog/product/cache/368/image/640x480/9df78eab33525d08d6e5fb8d27136e95/6/4/64357.jpg ?

Okay so Im not intirely sure what's wrong with my port in the front of the computer but I plugged it into the back, directly into the motherboard, and it's working fine now.... ._.

Sounds like the front panel connector wire is not connected to the motherboard.

Depending on the case, you might need to switch to AC'97 in BIOS.

Sounds like the front panel connector wire is not connected to the motherboard.

trace the wires back to the motherboard from the front panel, check it's fully in and secure at both ends. if you can carefully wiggle the wires near the motherboard connector while the PC is on (avoid touching anything else!) and headphones plugged in, check the sound for crackling noises which would indicate a loose or broken wire.
