iPod touch 5th gen ipod touch crackling/popping sound?

[SeeTheLights]

I recently bought a 5th gen white ipod touch from Target after selling my 2nd gen one. I got it all set up and did a restore from my old one so I could just keep my old apps and everything in tact. I got my music on there, but after I turned up the volume and started listening to it, the music had a popping/crackling noise like an old record on a record player. It seemed to only happen after I turned it up past a certain threshold. This never happened on my old ipod touch, and all the music is good quality cd rips. Any fixes? What should I do?

You have a 4th gen iPod touch; the 5th didn't come out yet.
