Poor, crackling sound output from both output ports. Why?

My ipod touch 4th generation has been acting strange recently, there is sound output from the headphone jack, however all of the low-end sound crackles. This is a recent issue, and at first I thought it was my headphones, however I played all of the songs that crackled through the same pair of headphones from a laptop, and there were no crackles. I have tried different headphones, even running the sound through a stereo and a bass amp (which is obviously meant for low end and never crackles) and they all crackled, but only when the sound was coming from the ipod. It also crackled when I plugged it into an ipod dock. I listen to a lot of dubstep type music, especially Deadmau5, and also make a bit of my own, and my headphones only crackle when they are plugged into the ipod, is the jack just faulty, or is it something deeper in the ipod? Again, this is a recent problem, Thank you.

Answer this question I have this problem too

Is this a good question?

If the sound is distorted no matter how you play the music, i.e. headphones, dock connector etc. it is not your headphone jack. If you check the teardown in the Step-by-step guides you will see that your ipod uses a "338S0859 chip. It's similar to the Cirrus Logic audio codec of the iPhone 4 (338S0589)." That is where your problem probably originates. A reflow MIGHT resolve this, if it is caused by a bad solder connection.

Why cant we just use regular solder instead of lead free and not have to deal with whiskering problems, haha. Thanks for the advice, however it seems to have stopped crackling, im not sure if it was because of the recent software update, but if it happens again, im breaking out the heatgun and ipod opening tools. Thanks again.
