Overriding the default output within an app


  • Subject: Overriding the default output within an app

New to Core Audio, as I'm sure you'll guess. I've been digging through docs, headers, sample code and the archives and I suspect it's just a result of density (information or my own) that prevents me from finding this.

As of 10.5, Cocoa's NSSound class has a method to specify the output device to be used for that sound. I can also, of course, in code change the default output device. What I'm looking for is the middle ground. Is there some relatively understandable and supported technique I can use to set the default output device for my app and then for the most part not worry about it thereafter?

I'm getting the impression, mostly from list postings, that the answer is: No. There really isn't a reliable means to say any audio generated under the auspices of my app will go "here" while everything else will continue to go "there." But I'd appreciate confirmation (or even better a correction) for closure.
