Most desktops don't require pulseaudio to work. Years ago it was someone
on this list who recommended I use Volti for a desktop mixer. Dealing with
a dependency in a desktop package on pulseaudio can be done by making an
empty package that"provides" pulseaudio and seeing what breaks. In my 
experience that is limited to desktop event sounds (in cinnamon) and the
original volume control which volti replaces.Perhaps I should make volti a
dependency in my empty pulseaudio package.

This is not recommended when dealing with onboard sound that does not
support a mono input or mono sound files will refuse to play. Most better 
onboard sound now has hardware mixing, but when there is no hardware 
mixer removing the software mixer means only one application at a time
can use sound and only in formats directly supported by the soundcard.
Ideally that would be jack but there are still too many things out there
that do not support or do not easily support jack, such as browsers.

On my netbook I use jack by itself when I need a sound server, but that's
because I need utter maximum video performance to get it to play 720p
video. I would not distribute those netbooks without pulseaudio.
