IPhone sound popping?

[Peruvian]

I am having some trouble with my iPhone, Everything seems to be ok apart from playing music. When a track is played, a random popping sound can be heard coming from the right side of the stereo output. I have tried this through many different output devices ? iPhone speakers/earphones and through the dock into an amplifier. I have tried various music sources ? downloads and rips from original CD?s, but the problem continues. The sound does not occur at the same point in tracks and it can be for 2 seconds or 10 seconds. Sometimes it will take several minutes before the problem happens. But other times it will do it every few seconds. This makes me think there is a hardware/firmware problem.

Any ideas? also its a unlocked, jailbroken 1.1.4...

Thanks P........

could it be anything to do with the bitrate of the music file? anyone?

Ok, it has nothing to do with the bitrate of the music...

Mine makes a popping sound when changing tracks, but I think it has something to do with soundcheck...

Have you tried turning SC on/off?
