Does that seem right, or am I missing something? 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). Col
