Thanks Fernando for your insights. I do expect it’s an isp issue, and that will be a to big challenge to address (they will just test access/connection speed). I wish Roon could buffer the stream so I will not notice it. Using the native BluOS Controller software of Bluesound/Nad (thus excluding Roon): same issues. Using Spotify: no issues, using Apple Music: no issues. It’s such a shame after spending so much in my setup a basic stream is not working.
RoonServer pulls down the next track from the music service at whatever rate is allowed by your ISP. If there is some channel contention on your local areas network, that can be enough to interrupt the core->endpoint stream; for instance, of some of the links for this traffic (ISP->core->endpoint) are wireless.
If the Nuc is new then it should be ok, but as it’s about 5yrs old, I would open it up and check for clogged fan, assuming it’s not in a Fanless case. I’m guessing it might be thermal throttling. Is it ruining hot?
I will check this wizardofoz. My nuc is in a rack, maybe not the best environment for a nuc. I will clean it and connect the nuc using a switch in the living room. If that does not work I will buy a nucleus , mini Mac or Mac Studio to replace the nuc. I already tried another Roon server (on my MBP - connection is wifi only) this works fine.
Have you had any further issues since your post? If you are still having difficulties, can you check to see if System Output on a Roon Remote or the HDMI output from the NUC also exhibits the same behavior?
I’m working on it. My plan is to update my server rack and get the nuc out of it. In the server rack the nuc is sharing the space with two pihole’s. This weekend I managed to migrate the pihole’s to my home server (same rack, different layer). I did switch off the pinholes and… the nuc issue disappeared! I still plan to clean the nuc, but this is already a result.
