Please help with Roon server/core issue

Hi AGers, 

So long story short: I only stream music (do not own any). I have Tidal and Qobuz streaming through Roon. And that is my problem. I started out using a M1 Mac Mini to stream but I often lost connection to Roon. So I bought a Small Green Computer i5 Sonictransporter and LPS. SQ improved but not the Roon problem. 

We have fiber optic to the house, a fully wired network and I have Silent Angel N8 switch feeding the SGC Roon server and my Lumin T2. No wifi anywhere. 

Finally after a couple of years, the problems increased to the point that 192/24 files crackle and pop. So I wrote to the Roon Community Forum under the Support section.

The Roon support person wrote back that:

*****We’ve activated diagnostics for your account and RoonServer and here’s what we can confirm:

1. Track downloads from Tidal and Qobuz’s servers are timing out with 24/192 FLAC files, and the prebuffer is barely ahead of playback. At times, it’s dropping out.
2. There are sample dropouts reported with by RoonServer on T2 Zone. These at times accumulate sufficiently to cause unnatural interruptions on the stream.
3. RoonServer constantly loses connection to upstream internet services due to network reachability changes in logs.

Your RoonServer’s intranet and internet connection appear to be struggling. How are you connecting your RoonServer machine to the internet?*****

Peter Lie from Lumin kindly wrote back and suggested I try changing my DNS to 8.8.8.8 - which I did. That did help a lot with SQ and speed but did not fully resolve the crackle and pop issue with 192/24 files. 

I would welcome any suggestions. 

Thanks, Nadine
