(OSStatus) error = -1500 in AudioToolbox Framework

问题

I am unable to play sound using AudioToolbox Framework. My line of code :

SystemSoundID soundID;
    CFURLRef  soundFileURLRef;
    OSStatus error = AudioServicesCreateSystemSoundID((__bridge CFURLRef)(aFileURL),         &aSoundID);

After debug Show error ((OSStatus) error = -1500).

回答1:

The error code -1500 represents the constant kAudioServicesSystemSoundUnspecifiedError, which has the description "An unspecified error has occurred.".

I'd double check that the URL can be read by your program, that the destination is a supported format, and that it is a valid, readable file.

Of course, googling kAudioServicesSystemSoundUnspecifiedError will give you some additional hints.
