In Fedora 12 + Gnome 2 I used to be able to modify the volume of each application seperately. Now, I'm on Fedora 20 + MATE 1.6.2, and this option is gone.
If I click
Notification Area > Sound > Preferences or
System > Control Centre > MATE Volume Control, a window opens that shows Master volume and other stuff like Headphones, Speaker, ACM etc., but I can't control each application's volume settings from here.
Is there any way how to achieve this? I'm in particular interested in dimming Firefox sounds quite, but only sometimes, and sometimes it's other applications, too.
