I just started using foobar2000 and to my delight found that it can push content to the Sonos system. This works fine on my Connect:Amp and Roam:SL, but something strange happens on the paired Plays (L and R).

Selecting one of the plays results in a UpNp failure in foobar2000. Selecting the other one works fine, but then content only comes from one of the Plays (in this case, “L”). I can tell from the music that it is only left-channel content; the right channel is being lost. I can’t see a way in the app (either desktop or mobile) to group the two Plays and have foobar2000 see them as joint stereo. 

Even more strange, when I stop foobar2000 and go to normal Sonos content (saved Shoutcast station, for example), the “R” Play is gone, and content only comes out of “L”. It’s almost as if foobar2000 knocked it off the network. I can restore “R” but I have to do it through re-pairing devices again. 

I found some foobar2000 components that seemingly addressed this issue, but they’re all Windows solutions, and I’m on a Mac. I realize this may be more of a foobar question and is not specifically Sonos, but I’m wondering if anyone else has encountered this and how it was solved.

Thanks!
