Linked Wiim issues (playing with optical, not with streaming)

[AudioAmore]

So this one is a head scratcher for me.

I use optical and line -in into my Ultra. I have an amp pro, and two Wiim Pro Pluses linked. The linked Wiims work perfectly.

However, today I tried streaming (via Roon as well as Spotify) and the linked players would not play. I can hear through the Ultra, but the others were silent. I tried streaming to the Amp Pro alone, and that worked perfectly. I then tried linking the ultra to the Amp Pro (basically the opposite of my usual set up) and, again, it only played through the "main" wiim.

I switched back to using the Ultra as the input device and linking the Amp Pro. Using the optical in, I had no problem at all. I switched back to streaming, and, again, it only played through the Ultra.

I tried changing the SPDIF resolution (which never gave me an issue in the past) and no change. When I played the test tone, it played through both the Ultra AND the linked Amp. But when I went back to streaming, same issue. Only sound through the Ultra, not the linked Amp.

I have tried rebooting all the devices. I uninstalled and reinstalled the app. All Wiims have been updated to the latest firmware.

I feel like I'm missing something unbelievably simple, but for whatever reason, I just don't see it.

I truly appreciate any help you can give me, if just to make me not feel like I'm crazy, lol.

Thanks!

I think what the faq you posted is saying is that multi room protocols are by and large different so it’s almost to be expected that you can’t mix and match…

Yeah...
