Microsoft is currently experimenting with a new audio control feature Windows 11 which allows users to control the volume of many apps from Quick Settings.

The volume mixer, as you know, is currently available in Preview build 25281 (opens in a new tab) from Dev Channel on Windows 11 Insider. It is compared to software like Discord and Ear Trumpet due to the similar possibilities of adjusting the volume levels for different sound sources. For example, you can adjust the volume on a Skype call while muting the music playing on Spotify and having WhatsApp somewhere between notifications. This is a level of manageability that is currently not seen as Windows 11 currently only offers universal customizations. Users typically use third-party apps like EarTrumpet to get this level of control.
