I don't find that app.  I find pasuspender, but it wants me to connect 
to a server.  I installed everything pulseaudio related except for the 
esound compatibility module.  That had a conflict with esound which is 
already installed.  Haven't tried removing pulseaudio yet, I suppose 
that is next.  Unless you have any other suggestions?
