How to choose the AudioQueue output device ?

Hi,

I'm trying to use another output than the default one for an AudioQueue, using AudioQueueSetProperty and the kAudioQueueProperty_CurrentDevice property (which is said to be read/ write in the doc and accepting a CFStringRef as parameter).

// hardcoded string for testing purposes AudioQueueSetProperty(myInfo.mQueue, kAudioQueueProperty_CurrentDevice, CFSTR("AppleHDAEngineOutput:0"), sizeof(CFStringRef));

It looks like from the console that it is sending a wrong message :

*** +[NSCFString length]: unrecognized selector sent to class 0xa00004a0


Any idea ?

thanks,
