Please let us know what your status is. @Martin_Webster’s clarifying questions will help us a lot too!
I decided to look at diagnostics real fast and at this point, Roon hasn’t seen your core in 2 days. I set it to notify me when you come back on and this will allow me to take a deeper dive into what Roon might see as the problem.
Pardon the delay getting a response back. To answer the question of streaming versus local tracks, it has been both. Going direct to Tidal or Qobuz on my streamer yields uninterrupted playback.
The Roon Core was offline for a time so that I could eliminate it completely from the signal chain. During that time I did not have any issues as mentioned above.
I’m home and playing a local track through Roon (Core is back in the signal path) and using a 16 bit/44.1 album about 11 minutes into playback and the first interruption took place. I’ve restarted playback to see how long I go without another disconnect.
As far as setting go. The DMS-800 settings are MQA capabilities: decoder and renderer, fixed volume, 0ms Resync Delay.
Core setup: the only option enabled is "Enable Roon Radio Notifications.
Services: Tidal and Qobuz are signed in and enabled
General: Core is connected. No other options are enabled on that page with the exception treating MQA encoded content. I have that set to “Treat MQA as better than CD quality, but not as good as lossless hi-re content.” I tend to not play MQA if there is a hi-res alternative.
Pushing send on this now. I’ll get back when I have more to add.
Please do let me know how your efforts in swapping out the switch go. I see errors in the logs that indicate that network devices are in fact dropping connection. Diagnostics shows you trying to enjoy the Talking Heads (a great choice) and then the connection drops.
There is another possibility that Roon’s SW is to blame and I will list the steps to address this below. It’s a relatively simple thing to try and would serve to eliminate the SW as a possibility!
