In Windows 11 the old volume mixer was "removed" and instead a new mixer was added to the settings app.

I really don't like this due to it's HUGE size in comparison. Luckily the old exe is still available in system32, so we just need a convenient way to open it.

Thats pretty much what this is, this repo contains an application that add a new icon in the system tray that can be used to launch the old mixer. It also comes with a few optional quality of life improvements, you can turn them on and off if you right click on the icon

To install it open a powershell window and type the command

winget install PopeenCom.ClassicVolumeMixer

Alternatively you can download it from the releases page
https://github.com/popeen/Classic-Volume-Mixer/releases

If you get smartscreen error (blue box popup) this is because the file has not been signed and is still to new. You can click on "more info" and then "run anyway" to run it, this is only needed once.
