我一直在iOS 6上使用ObjectAL 2.2一段时间没有任何问题但是在iOS 7中，我得到了这个：
OAL Error: +[ALWrapper createContext:attributes:]: Invalid Value (error code 0x0000a004)
OAL Warning: -[OALAudioSession onAudioError:]: Received audio error notification, but last reset was 0.000820 seconds ago. Doing nothing.
OAL Error: +[ALWrapper genSources:numSources:]: Invalid Operation (error code 0x0000a004)
OAL Warning: -[OALAudioSession onAudioError:]: Received audio error notification, but last reset was 0.001542 seconds ago. Doing nothing.
OAL Error: +[ALWrapper getSourcef:parameter:]: Invalid Value (error code 0x0000a003)
OAL Warning: -[OALAudioSession onAudioError:]: Received audio error notification, but last reset was 0.002222 seconds ago. Doing nothing.
我也尝试了“前沿”版本，但它有同样的问题。可以采取哪些措施来解决问题？

这似乎仅在iOS 7模拟器中存在问题，但在实际设备上，没有更多错误。
