support for multiple audio devices

[Tim Curtis]

moOde can act as a UPnP renderer or A/V media server (DLNA server) but not as a UPnP control point. This role is not supported by the UPnP stack that moOde uses. https://www.lesbonscomptes.com/upmpdcli/

You would need a control point app like Linn Kazoo etc to be able to use your Receiver/Amp as a renderer.
