It is the other way round. Audirvāna needs to “see” your Rossini and your music (if hosted locally). If you’ve set up MinimServer correctly then the device running Audirvāna just needs to be on the same subnet (i.e. the third segment of the IP address needs to be the same) as the MinimServer device and the Rossini to see them. If this is true then per above Audirvāna should recognize the Rossini and configure itself automagically.
