No it's up to the application to decide how it handles the cork events.
If it would prefer to stop itself, then that's up to the app. We should
not be deciding policy for this behaviour in PA, just indicating that we
want the application to stop producing audio.

For more fine grained media player control, I'd recommend using
something like MPRIS or similar.

Just look elsewhere in the code for examples of how to upload samples
to the cache. But as a hint, pa_scache_add_file()

It's up to you. You could just pass a full path in the module argument
or default to /usr/share/sounds if you prefer. Perhaps it's even worth
adding a "suppressed-sound" to the Sound Theme Specification? I think
that's more complicated than it needs to be at this stage however.

Again this is in the code but as a hint pa_scache_play_item();

(I appreciate we don't really have great devel docs here, so the "it's
in the code" argument is pretty weak!)

Take care
