Doesn’t seem so, which is bad…
I Believe if this was a reality i would have already bought 2 more play 5 to replace my wired amp & speaker set up. Streaming the output from these apps to a multi room event would be a match made in heaven, its what Sonos set out to do isnt it?
I can’t believe there are 15 threads on the topic of output to sonos and there is nothing substantive in terms of guidance on integration or workarounds.
