Abstract
A portable media player configured to selectively enable or disable one or more input controls, such as volume controls, is described herein. In some examples, the player contains a physical button or switch that provides for the selective enabling or disabling of input controls. In some examples, the player is configured to dynamically determine when to enable or disable input controls based on information received about the player or characteristics of the player. Other embodiments are also described and claimed.
