Correct, Availability.h was introduced in Mac OS X 10.5. 10.4 and earlier must use AvailabilityMacros.h instead.

As far as I can see in

https://github.com/erikd/libsndfile/commit/49017a1b08322770e91ba597d4b8e12b20f4ae14

the error message refers to OS X 10.8, a.k.a. Darwin 12. I'm not sure which new audio API they're referring to.

I agree, it prints the error for me on Mac OS X 10.6 as well. It doesn't seem like it should be doing that.

It is because sndfile-play support for OS X 10.7 and earlier was removed in this commit:

https://github.com/erikd/libsndfile/commit/50a4098e9ffe56bcfd2aab06a14769ff9ffbbac2

I'm not sure why they did that, since they never wrote code for sndfile-play for OS X 10.8 or later, making it completely useless on all versions of macOS.
