I think this is a request for enhancement. Spent some time searching the community and didn’t find this already discussed.
It would be nice if the Sonos PC and Mac apps could be enhanced (or maybe a separate app created) so that a PC or Mac and its connected speakers could serve as a Sonos “speaker.” That is, it would appear in the Sonos app in the list of devices in the Sonos system and could be grouped with other Sonos speakers.
For example, when I play music from iTunes on my PC, using AirPlay I can send the sound to any or all of my Sonos speakers and the computer’s connected speakers, all nicely sync’d. When I’m playing music from Pandora using the Sonos app, I’d like to be able hear that in the room where my computer and its speakers are.
Well, looked some more and found this. Sounds like the old-timers know this (fairly obvious) idea has been around and rejected for years. Also, it sounds like one could put a Port in-between the PC and its speakers and accomplish this at considerable added cost and with increased complexity in the normal use case.
Guess I’ll put this out there anyway and see what pops up.
Edit: Well, just found this including including an older, broken link from buzz: "very long, sometimes tense thread" and this. And it is true that my request came from a desire to accomplish this at less expense and without more hardware. And, unlike many, I do get it that the controller app isn’t “playing” the music -- it’s going directly to the speakers from, for example, Pandora (to some degree “through” Sonos, somewhere).
So, please consider this request withdrawn.
