No changes in the hardware requirements but an additional check was added to Receiver config to ensure that MPD mixer type is set to either Hardware or Fixed (0dB) volume.

Code:

The Receiver requires an audio device that supports Hardware volume.
NOTE: Mixer type must be set to Hardware or Fixed (0dB) in MPD Config.
