I download and listen to a lot of podcasts on my iphone and maybe a month or so ago I noticed during playback on my iphone I would get like an eletronic buzz kind of sound. It would only last a brief second and happened randomly. Sometimes only once or twice during an hour podcast, others 10-20 times. I played back the podcasts on my PC in iTunes and the distortions happened the exact same times on that they did on the iPhone. Can anyone suggest anything on how to fix the issue cause I haven't a clue.
