iPad 3 speaker crackle
Hi guys, I got my new iPad on Saturday, I absolutely love it. However today I was using the app catch up tv on Dave and I noticed the speaker was crackling, but doing so weather low volume or full volume, I switched to my iPhone 4s and loaded up the same app and same channel and it was doing the same so I thought it might just be the channel. However I've noticed since that my iPad is slightly crackling on certain songs full volume, and some YouTube videos. What should I do? Obviously I haven't spent this much on an iPad for it to have crackly speakers. I'm really displeased about it atm, so should I wait to see if it gets worse or try to take it back?
Thanks in advance
