Please Help to open AMR file.

[mmainac]

I'm trying to open AMR file using this function:
OSStatus status = AudioFileOpenURL (
soundFile,
fsRdPerm, // read only
kAudioFileAMRType,
&audioFileID
);
soundFile is the (CFURLRef) type and having the url of the file in Document directory.

This function shows error in opening, it says
Error loading /Library/QuickTime/Sonix SN9C201 WebCam.component/Contents/MacOS/Sonix SN9C201 WebCam: dlopen(/Library/QuickTime/Sonix SN9C201 WebCam.component/Contents/MacOS/Sonix SN9C201 WebCam, 262): Symbol not found: _SCDynamicStoreCopyConsoleUser
