Which version of Xcode you use to build your product should not affect its ability to instantiate audio components, _unless and perhaps_ the version of Xcode affects which SDK you're linking against. Your sample code doesn't involve anything from the Core Audio SDK, so we can rule that out.
If you're running on 10.9 and linking against the 10.9 SDK, then you might get different behavior than if you had linked against the 10.8 SDK. I would start by cleaning the Build Products directory and triple-checking the SDK being linked against. If that fails, I would take the same executable and run it on 10.8 (making sure it's linked against the 10.8 SDK). If all else fails, I'd check the 10.9 release notes for anything related to Core Audio, and file a Radar if necessary.
In short, this sounds like an OS issue, not a an Xcode issue.
