Actually pulseaudio is not started by the shepherd, it's started by your user 
processes. Basically, when they try to use it and it's not present, it is 
automatically started so they can talk to it. Killing it won't help, because it 
will be restarted by the first app that tries to play sound.

You could make it crash at startup, but then you will get no sound at all. 
That's what happens with the home manager if you don't implement a workaround. 
Make your home read-only and you can get rid of pa… and all audio with it :/

The pa service is only to set a default configuration in /etc, but it's always 
overwritten by configuration in your home (that's why a read-only home crashes 
it). There's no process started or managed by it.
