Aplicativos não aparecem no Volume Mixer
Esta funcionalidade foi removida do Windows 10.
Você pode usar um aplicativo chamado EarTrumpet em vez disso:

The app is very useful in instances where you are playing a modern game on Windows 10 and at the same time listening to some songs on the Edge browser. You can lower the volume of the game and enjoy the song at the same time. This is just one of the many scenarios where it can prove to be useful.
