Seriously?  OK.  ESD, the Enlightenment Sound Daemon, is a server that
programs connect to whenever they want to play a sound.  There are a few
reasons for such a thing, but the main ones are:

  1) The old-style /dev/dsp only allows one process to use it at a time.
     You couldn't listens to MP3s and still get audio alerts from other
     programs at the same time.

  2) It serves as a compatibility layer to provide a standardized sound API
     across multiple operating systems so that programmers wouldn't have to
     know the intricacies of, say, Linux, FreeBSD, and Solaris just to add
     sound to their program.

  3) Networking.  You can run ESD on one computer attached to a good sound
     system and point your client programs at that server to play their
     sound.  Very handy if you want a tiny, low-powered "sound server"
     attached to your home stereo.  For example, you could set XMMS to
     stream audio to that computer so that you hear your MP3s on good
     speakers, but still hear audio alerts on your PC speakers.

Having said that, almost everyone hates ESD because of various performance
and audio quality problems.  KDE's "artsd" is generally regarded as a
superior replacement, although it also has its detractors.
