Probably that ALSA support wasn't compiled into MPlayer...

... which this list seems to verify.  You'll likely need to install the
appropriate developer package for ALSA (likely the library package with
'-dev' or '-devel' added on), and recompile and reinstall MPlayer.
	That's assuming you compiled MPlayer from source to begin with. 
If you used a packaged binary and there's no separate package to add
ALSA support, then see your distribution/OS's documentation for how to
file a polite feature request to the packager.
