Question

I asked this previously but Jeff Atwood moved my question to superuser.com. I need a answer programmatically…

I want to use built in speakers and usb speakers simultaneously on MAC OS X 10.6.

I want to play different files on these (I do not want to play same file on both speakers).

Is it possible using cocoa (QTMovie or something else?) or anything else?

I have checked the portaudio thing but didn’t get how this works! 🙁

I have also tried to send some data to the USB speakers but the sample “USBSimple Example” downloaded from apple’s site didn’t worked!

Answer 1

ok I got it myself…

NSSound *airplaneSound = [NSSound soundNamed:@"Aura Cleanse-1.wav"];

[airplaneSound setPlaybackDeviceIdentifier:theCFString];
[airplaneSound play];

I can pass the audio device uid in the setPlaybackDeviceIdentifier to play this sound on a particular device

Please find here how can you get audio device uid
