However, you will never be able to select audio devices for your apps with the Volume Mixer. This new “App Volume and Device Preferences” section works just like the old Volume Mixer, allowing you to adjust the volume for individual applications. This is a useful feature that you should have if you want to do more than one task at a time, and you don’t need to remember to connect speakers/headphones depending on your use. Windows 10 saves these settings and automatically changes the audio output device. So let’s say you’re watching online content in Firefox with headphones while the speakers are being used for PC gaming, you can customize it without having to switch between the two sources manually. This means that if you have speakers and headphones, you can choose which ones to use depending on the application and adjust the playback volume for each of them.
Windows 10 supports playback of multiple audio streams based on individual applications.
