Use the MRM library classes to implement the MRM feature on your Alexa Built-in device, including the following functionality:

To get started with implementing MRM on your device, contact your Amazon Business Development representative. While the Named Device Targeting feature of the Alexa Voice Service (AVS) allows you to play music from a single named Alexa Built-in device, MRM extends that capability so that users can play music from a set of synchronized Alexa Built-in devices. For example, a user can say 'Play Jazz in the Living Room,' to start playing jazz music in their living room on multiple devices. The Alexa Multi-Room Music (MRM) feature enables users to choose a specific Alexa Built-in device to play music.
