I'm not particularly familiar with any audio API other than Core Audio, so I'm not sure how comparable the feature sets are, but per-stream volume and such are available.
Core Audio is not particularly close to the hardware. I think it's roughly similar to a sound server type of architecture. There's no problem with multiple apps producing audio, or anything like that. It's pretty "virtual"/abstracted.

What makes you say the OS X branch is closed?
Apple has links at http://www.opensource.apple.com/ to the OpenAL that ships with each version of Mac OS X, although Creative seems to have reorganized their site and Apple's links are dead. Still, the above SVN URL should be current.
