I just noticed that when I was trying to unlock my iPod and while trying to enter my passcode, the keyboard click sound was really loud, as if the volume has been cranked up to max. It's random though, at times the click sound is just at a normal volume but sometimes it will be loud. I'm just concerned if something is up with my iPod if it's a software glitch I'll ignore it. iPod 5th Genenration iOS 6.1.3 Sound/audio play as per normal during music, videos and YouTube nothing is amiss just during the passcode. Anyone experience such a thing?
