iPod 5th gen sound issue (distortion?)

Ahh yes. The 13 in his name threw me off.

Ok, so I disabled the prevent clipping feature in rockbox and the problem didn't return. Which tells me that it is  more than likely a bad smt joint or whatever you call it. Is it possible that the ipod just needed a little warmup time? Like, maybe it hadn't been used in a while and just needed a little usage to get flowing good again? Either way, it seems to be all good now. If it were the smt joint though, would an imod definitely remedy the problem from ever returning? I'm looking into getting a diy imod done soon. Thanks.
