Hi Stephen,
        as others have said PulseAudio and Jack are somewhat the same 
thing and
        they complements one to each other.
        They are all "sound server" like ESD and aRTS but with some 
difference in
        the target audience:
        * PulseAudio is a desktop sound server with implements stream 
          network transparency, sample caching, and more
        * Jack is a pro audio sound server that can connect different 
          applications together with an emphasis on latency and sample 
        and from the PA or Jack point of view Alsa is just the sound card 
        You can read some more about PulseAudio here:
        And to be complete not everyone likes PulseAudio.
        The response from Lennart Poettering main PulseAudio developer 
(in this post he
        explains better than me the scope of PA):        
        Kind regards,
