The OpenAL audio backend is implemented and tested on all platforms.
This means one and the same audio backend is used on all platforms (Windows, OS X, Linux) and more importantly it is (hopefully) a more stable solution. Particularly on Linux and OS X platforms.
The downside is that another external dependency may have to be installed.

For Linux (Ubuntu!) you install the following package: libopenal1
Small bugfixes, incremental improvements. Expect more rapid development here soon.
