Allow to set volume of non-active pulseaudio clients
Currently, pulseaudio doesn't let you set the volume of non-active clients (AFAIK). After several years from being asked here a guy named Roland Haas developed this project to aim this particular issue (I filed there a counterpart issue). I'm not sure if should be added to
pavucontrol or elsewhere but certainly would be neat to have it built-in in pulseaudio.
