Best suggestions for a user on a linux machine, with a house full of devices (Windows, Mac, iOS, Adroid) for a rock-solid wireless streaming solution? To this point I have found DLNA/UPnP to be very unreliable (sometimes servers and/or endpoints show up, sometimes they don't). Roon is rather expensive for what it does, although it does have a good reputation for reliability in streaming. I have quite a few Chomecast audios which work ok but they seem to be unreliable in terms of whether they are seen or not by control points. Is there anything out there that just works? Thank you
