What does this gdb output mean?

Question

I've got a button that plays a sound, and it seems to work perfectly fine on the simulator, but i'm getting this message:

And i've had reports saying, on some devices it's not playing at all.

Just wanted to add I'm seeing this same issue when playing HLS video streams in a iOS project using ARC. — James J, Mar 27 '12 at 19:22

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.

Still seeing this issue with LLDB but the annoying delay is gone. – stigi Mar 07 '12 at 14:37

Looks like this is caused by an internal exception being thrown within AVFoundation on the Simulator. Disabling the "All Exceptions" breakpoint stops the debugger breaking at it and the sound does play, as suggested by Brandon Williams' answer. (Or force the debugger to continue repeatedly and the sound will eventually play.) – Chris Miles May 02 '12 at 00:33

I am still seeing this problem in Xcode 4.5 and with the iOS 6 Simulator + iOS SDK 6.0, no matter what workarounds or suggestions I try to move past it. Hmm ... – Joe D'Andrea Oct 12 '12 at 15:47

I found a temporary workaround to this problem: simply turn off breakpoints before playing the video. Then it works fine in the simulator.

The following code can be used to test on simulator.

if (beep == nil)
    NSLog(@"audio player not initialized");             
else if(TARGET_IPHONE_SIMULATOR) 
{
    NSLog(@"beep play"); 
} 
else
{
    [beep play];  
}

This Problem May occur if you incorrectly import a Mac OSX framework instead of iOs framework. Removing the Mac OS framework worked for me

Use the AVAudioPlayer as ivar in head file with strong : @property (strong,nonatomic) AVAudioPlayer *audioPlayer For me this works.

This is a problem many people are having. I didn't find any solution to this yet.

I strongly suggest to file a radar. Here's mine http://openradar.appspot.com/radar?id=1466402

Don't worry on Apple becoming silent. I still get feedback on bugs. But this one is so obvious. They should at least figure out the duplicates :( – stigi Feb 14 '12 at 13:28

What Till says is absolutely right. But when using ARC, this problem might correlate (without a causality) with another problem: If the AVAudioPlayer actually doesn't play any sound, this might be interesting for you: https://stackoverflow.com/a/7744831/838068
