As @duskwuff says, you probably won't have any joy trying to access sound devices using /dev devices on OS X.

If, as you say in your comment above, your goal is cross-platform portability then perhaps PortAudio might be a solution.

From their homepage:

PortAudio is a free, cross-platform, open-source, audio I/O library. It lets you write simple audio programs in 'C' or C++ that will compile and run on many platforms including Windows, Macintosh OS X, and Unix (OSS/ALSA). It is intended to promote the exchange of audio software between developers on different platforms. Many applications use PortAudio for Audio I/O.

On OS X I believe they use Core Audio and on Linux they use OSS/ALSA.
