It is another layer of software on top of alsa. It does some interesting
things. It
can be thought of as a "replacement" for the old ESD.

I have two sound cards. With pulse, I can plug the speakers in one card and
the headphones
in the other and switch on the fly between them. Also, I can switch users
while playing a song
and when I am back the song is still playing.

But MythTV does not work with pulse, even with the alsa plugin. It has to be
patched.

This is what I got so far (some applications work specifying ESD as the
output driver):

MythTV: NO sound at all (therefore, pulse can not be a global default for
me)
mplayer (patched): OK
mplayerplug-in: OK
rhythmbox: OK
amarok: OK
xmms: OK
audacious 1.4: OK with ESD (stutters a lot with its native pulse plugin).
mpd 0.13: NO sound (it has the plugin, though).
ampache (flash player): OK
xine: OK with ESD. Using its native pulse plugin, the sound disappears after
a few seconds.
vlc: OK whith ESD (no pulse plugin available yet).
