What do you mean "When you set it up"? pavucontrol can change the volume 
of any running stream - or are you talking about from an API level? 
Regardless you can change the volume of a running stream no problem.

The tricky bit is trying to catch a stream that is very short - like 
sound events. To adjust their volume is pretty tricky!

This limitation is being addressed tho'. (AFAIK).
