If alsa support is compiled in, then alsa will be preferred over SDL.  
As long as SDL is supported in the build (which is the default), then 
you will be able to at least use alsa.  Whatever SDL uses by default 
depends on what the configuration is.  IMHO, just relying on SDL to pick 
the Right Thing is best because that's a choice that was made by the 
distribution so presumably it's whatever works the best on the given system.
