Well, we will need specifics as to your hardware before we can begin to help identify the cause, and so, a solution.

Well the sound card is intergrated onto my H67M-D2B3 Gigabyte motherboard, CPU i5 2500k,Ati Radeon HD 5770.I m running dual boot with Win7 and have no problems with sound there.

Integrated. Okay, open a console and type:

lspci | grep udio

Copy and paste the result.

Okay i just plugged my USB headphones and sound is normal!!But the second i pull headphones off its choppy again.I m pretty sure its not hardware fault because everything works fine in W7.
Update:Lol this weird.So my headphones have "attachment" so that you can choose between using USB or jack plug.I took that attachment and plug the jack plug from speakers into it and the sound is perfect!!!But i still need help fixing this since i dont want to use it like this.
