Not sure what the issue is in your case. Is it always the same track in the same place for you, reproducibly? If so the track may be corrupted in the copy on the server that serves you. I am in Germany. Does it work in the Qobuz app for you?
If the track with the issue is not always the same, could be your Qobuz servers are slower than mine, or the path from the Qobuz servers to you through the internet has inconsistent performance (even though your uplink may be consistently fast). Or, lastly, something in your network after all that’s intermittent, but probably unlikely as you have ethernet to core and endpoint.
Yeah, if for you it’s always the same track in the same place in the track, it hints at file corruption. On the other hand, if the files on the Qobuz server were damaged, they would also be damaged when played through the Qobuz app - unless, of course, if there are different servers from which Qobuz streams via Roon than in their app. That’s opaque to us, so we can only guess. Understandably annoying.
I guess someone from support will have to take a look at this, but at least we saved them some work narrowing it down
