Cool, thanks, Jim.

I wrote to Jesus at Sonore today and he wrote back and said that they expect to be shipping the OpticalModule out the 1st or 2nd week of June.

I tried a new switch yesterday preparing for the Opticalmodule device I have on order. Dropouts and Roon error messages galore. Back to the non-optical capable device at least for now. I', considering canceling my order.

I think the problem may be with the Orbi network, Jim. Any info if an Eero mesh network will work better?

BTW, its very clear that mesh networks don't play nice with a range of networked devices. Ring says that their Video Doorbell basicially do not work well mesh WiFi networks, they recommend a Wifi Extender instead, e.g., a TP-Link, etc.

i agree that it could be the Netgear Orbi mesh network. Everything else works so well with great coverage that I am a bit reticent to change over to something else just for a small improvement in audio SQ. What Orbi support could never explain is why I needed to add a switch in the first place when the Orbi Router and satellites have enough ports to do job in the first place.

I run an Eeros mesh, and it has zero issues with Ring and their self diagnostic indicates this as well along with others.

Is the Orbi satellite wired or wireless? If it’s wireless and you coming out of it into your DCS bridge, that may be where it’s an issue.

That's great to know, thanks!

Both my DCS Upsampler and SonicTransporter i5 (where Roon and my music reside) are hardwired to a switch that is hardwired to the main Orbi Router.

So it's Orbi router - Trendnet switch - dCS Upsampler. Correct?

I believe the Orbi router has 1000Mbps Ethernet ports.

What's your Trendnet switch model? Is it a 1000Mbps or 100Mbps switch?

What speed is your dCS Ethernet port running at? 1000Mbps or 100Mbps? If your Trendnet switch is a 1000Mbps Ethernet, it should show two different colors for the speed of a particular port so that you can find out it's running at 1000Mbps or 100Mbps.

If any of the above is running at 100Mbps, then one possible cause for the problem you were having might be related to how the 1000Mbps is made to run at 100Mbps, resulting in different network traffic patterns. The insertion of a switch to cure Roon playback is a common solution for another brand of network amplifier. Before that becomes common knowledge, Chris Connaker also found the same solution for an unspecified endpoint, described in a thread he created in his own forum.
