Hi guys ! I come with a difficult question ! Mac Mini 2014 and/or Macbook Pro retina 2014 Currently I can output music from iTunes to multiple airport expresses. I would like to do the same from the OS Directly. (To play soundcloud music) The only option I've found was to airplay the sound to 1 airport express at a time plus the built in output, wondering if there was a way to have multiple airports working together. (2 for the moment) thanks in advance, Hope i'm in the right section... not really sure where to ask this.
