Audio hardware company Realtek is in the process of bringing their Realtek Audio Control app to the Microsoft Store.
The app, which has all the features as the legacy win32 app, lets you adjust audio device effects and the other features of your sound hardware.
While the app is available in the Store, it does not appear ready to install yet, as this appears to invariably fail.
It is still however good news that a driver and codec company is embracing Modern applications, which is hopefully a sign that we are reaching a tipping point, after more than 3 years, that Modern Store applications should be the default for any new or redesigned app.
The applet can be seen here.
