--- Comment #1 from Tanu Kaskinen <tanuk at iki.fi> ---
The purpose of module-stream-restore is to restore the previously set volume
when an application reappears. Using the pid as the identifier would defeat
this purpose, because when an application is restarted, it would look like a
different application if it was identified by its pid.

Sometimes it would be desirable to opt out from restoring the volume for
certain instances of applications, which is maybe what you'd like to do. We
don't have a nice way to do that. It's possible, however, to work around that
by setting an environment variable when starting an application:
PULSE_PROP="module-stream-restore.id=foo".

If you want to disable volume restoring altogether, add the parameter
"restore_volume=false" for module-stream-restore in /etc/pulse/default.pa, or
comment out the module from the configuration (that will have the additional
effect that stream routing won't be restored either).
