One use case for Pulse is recording the audio output of another application that
won't work with Jack. Makers of "consumer" soundcards and onboard audio 
stopped including recording the output as a hardware option at about the time
Windows Vista came out, and removed support for existing cards doing this 
from their Windows drivers. This was at the request of Hollywood. Pulseaudio
defeats this crude attempt at DRM utterly. This was the use case that put it 
back on my machines, to defeat efforts at Youtube to interfere with downloading
music videos (or otherwise saving the sound) from their site (over Tor in my case).
