NSSound soundNamed:

My code allows the user to pick a sound file ( usually from /System/Library/Sounds but could be from anywhere ) and then uses the FSRef for the file to get a CFStringRef with the file name ( via FSGetCatalogInfo and CFStringCreateWithCharacters ) in it. That CFString is then fed into the PlaySound() wrapper ( nipped from Bernie ) shown below. PlaySound() works fine if the sound file ( usually an AIFF ) is in the application bundle but fails for sound files selected from system sound folders such as the one mentioned above. I’ve reduced the failure to soundNamed: not finding “Glass.aiff” in /System/Library/Sounds( the CFString fed to PlaySound contains “Glass.aiff” as expected ). Xcode docs for soundNamed: indicate it should find the sound:

~/Library/Sounds
/Library/Sounds
/Network/Library/Sounds
/System/Library/Sounds

Failing a mistake ( likely ), my thought is to convert the FSRef to a CFURLRef and feed to a wrapper function that can explicitly find the folder instead of relying on soundNamed:’s default search. Other ideas?

'---------------

BeginCFunction

void PlaySound( CFStringRef filename )

{

NSAutoreleasePool *localPool = [[NSAutoreleasePool alloc] init];

NSSound *sound = [NSSound soundNamed:(NSString *)filename];

[sound play];

[localPool release];

}

EndC

toolbox PlaySound( CFStringRef filename )

PlaySound( @"Glass.aiff" )

RunApplicationEventLoop()
