解决方案
这是 iOS SDK 5/模拟器的一个已确认的错误 - 一旦模拟器尝试播放声音(来自电影或任何其他声源)就会发生.不过不用担心，在实际设备上不会有问题.
您提到了用户在使用您的应用时遇到问题的实际报告 - 这些问题与您在上面发布的问题无关.
此问题由 Apple 以错误 ID# 10555404 提交.我自己确实提交了一份报告，最终被确定为上述错误 ID 的欺骗.
该问题目前一直持续到并包括 Xcode 版本 4.4.1 (4F1003)、iOS SDK 5.1.
更新
这个问题最终在 Xcode Version 4.5 (4G182), iOS SDK 6.0 中得到修复.
注意
当与 iOS 5.1(或更低版本)模拟器结合使用时，即使在 Xcode 4.5 版中该问题仍然存在.

And i've had reports saying, on some devices it's not playing at all.
解决方案
That is a confirmed bug of the iOS SDK 5 / Simulator - happens as soon as the simulator tries to play sound (from a movie or any other sound source). Do not worry though, it won't be a problem on the actual device.
You mentioned actual reports of users having trouble using your App - those problems are not related / connected to the issue you have posted above.
This issue is filed by Apple under Bug ID# 10555404. I did file a report myself which has finally been identified as a dupe of the mentioned bug id.
The issue currently persists up until and including Xcode Version 4.4.1 (4F1003), iOS SDK 5.1.
Update
This issue is finally fixed within Xcode Version 4.5 (4G182), iOS SDK 6.0.
Note
The issue persists even in Xcode Version 4.5 when used in conjunction with the iOS 5.1 (or lower) simulator.
