That's right... but module-volume-restore remembers the sink for the client
between client connects. So the next time the same client connects,
module-volume-restore will not assign its streams to the default sink but
one that it has saved.
Basically, I need a module which assigns the default sink to a new
connecting client and passes all its streams to that sink regardless of the
current default sink (by default pulseaudio uses the default sink for any
new sink-inputs). However, if the client disconnects and connects again, it
should use the new default sink for the streams of the client
(module-volume-restore preserves the sink for the client between client
connects). The module could be called some thing like
module-preserve-client-sink or something.
