Deleted my hack and downloaded the 5.x version Juanito made. It works with alsa on my box (previously had alsa installed and working with XMMS). When I right-click on the Audacious panel and select Preferences the Current output plugin dropdown shows as ALSA Output Plugin. Besides alsa, I have Firefox 27.0 (used Firefox-get to obtain it), jdk7 (obtained via java-installer), Flash, evince2, flpicsee, and fluff -- a very minimal setup. Possibly Audacious is missing a dependency that I happen to have from one of those apps? Also I'm running xorg.
