 ## Understanding Middleware
 
-Middleware are functions that return an object, a class instance, a prototype, etc, scoped to the Player with methods matching those on the `Tech`. There are currently a limited set of allowed methods that will be understood by middleware. These are: `buffered`, `currentTime`, `setCurrentTime`, `duration`, `seekable`, `played`, `play`, `pause` and `paused`. These allowed methods are split into three categories: [getters](#middleware-getters), [setters](#middleware-setters), and [mediators](#middleware-mediators).
+Middleware are functions that return an object, a class instance, a prototype, etc, scoped to the Player with methods matching those on the `Tech`. There are currently a limited set of allowed methods that will be understood by middleware. These are: `buffered`, `currentTime`, `setCurrentTime`, `setMuted`, `setVolume`, `duration`, `muted`, `seekable`, `played`, `play`, `pause`, `paused` and `volume`. These allowed methods are split into three categories: [getters](#middleware-getters), [setters](#middleware-setters), and [mediators](#middleware-mediators).
 
 There are a few special methods that affect middleware: `setSource` and `setTech`. These are called internally by Video.js when you call `player.src()`.
