AudioServicesPlaySystemSound muted on simulator xCode 6 GM

问题

I run the following code on simulator and I don't get any sound:

NSString *soundPath = [[NSBundle mainBundle] pathForResource:@"pageflip" ofType:@"mp3"];
NSURL *soundUrl = [NSURL fileURLWithPath:soundPath];

AudioServicesCreateSystemSoundID((__bridge CFURLRef) soundUrl, &_soundEffect);
AudioServicesPlaySystemSound(_soundEffect);

The code has been successfully tested on xCode 5 and iOS 7. Libraries imported as required.

I've logged the soundPath and it returns the correct location on the filesystem.

Has anyone experienced a similar issue?

回答1:

This is an issue with the simulator. On a device it'll work as expected.

回答2:

I have a similar issue now. My AudioServicesPlaySystemSound was working until the XCode update to 6.0.1. One could assume that there is something broken in the update.
