Microsoft along with Google is exploring a way to make each web apps to have separate media controls on Windows and Mac.
Web apps are becoming more and more like native apps, thanks to the advances in Progressive Web Apps (PWAs) technology. One of the features that can enhance the user experience of web apps is System Media Controls, which allows users to control audio playback from the OS level. Microsoft along with Google is exploring a way to make each web apps to have separate media controls on Windows and Mac.
Current System Media Controls Behavior:
Right now, all audio sources from the browser, including tabs and web apps, share one System Media Control instance. This means that if you have more than one source playing audio at the same time – for example, a tab in the browser and a web app the Windows or macOS media control box will be able to show only one source.
