Set a maximum volume for your media player

This blueprint allows you to set a maximum volume for your media player. If the volume is raised above the level you’ve set, it will automatically back down. The motivation for this is my kids constantly raising the volume on the family room tv to ear-splitting volumes :slight_smile:
