I have a problem that has surfaced since installing the latest OS update on my iPad 2. The audio in various apps (Pandora, Slacker, Tune-in and other radio apps) frequently pauses on its own. At first I thought I was having a wifi interference/dropped signal problem. But the wifi is both strong and fast. The router is about three feet away from the iPad and the same apps on my Kindle Fire and Android smartphone (Droid Razr Maxx) don't suffer from the same problem. Even tried changing to the 4G/LTE network with my mobile hotspot as the data source. No dice. Same problem. My next thought was that notifications were somehow to blame since they typically mute the audio briefly when I receive email or news updates. But I've tried turning off the notifications (even dropped the email accounts to see if they were somehow causing the problem.) Again, no dice. The problem continues. However, it does seem more likely to occur when a notification or calendar update occurs. In some cases I've found if I leave the iPad alone the problem sometimes fixes itself with the audio returning. But not consistently. I've only noticed this problem since installation of the latest 5.1 OS update. Given that that update has some audio-related features I'm wondering if that's where the problem lies. Anyone else having a similar problem?
