Thanks for the status update @Vince_Deters, we’ll bring your case to our development team for further review. We should have more information to share before the end of the week!
Ok, after the last reboot it has now added everything back and my library is good. Also, the Library → Library Maintenance → Clean up library top check box now shows a reasonable number of deleted files (that I probably explicitly deleted myself). This is all with IPv6 re-enabled and my ethernet switch re-introduced into the server’s network path, so neither one of those had any effect.
The root cause is still a mystery to me so I would appreciate any further feedback.
Hi @Vince_Deters,
We’re glad Roon is working for you again. We’re still waiting for feedback from the development team about the ticket we made for this case. Once we hear from them we might be able to give you an answer about the root cause of the issue.
I’m part of the Roon dev team, and I wanted to explain our best understanding of the cause of the problem here:
- until build 1462, Roon had a bug which could cause it to believe that a Qobuz account had 0 tracks and albums on it.
- most of the time Roon does only an incremental sync with Qobuz to determine what tracks and albums are in your favorites: we send them a timestamp, and they send us a list of all the changes since that timestamp.
- every 72 hours or so we do a full, non-incremental sync with Qobuz.
so, my belief is that sometime before we released build 1462 the bug caused Roon to believe you had 0 Qobuz favorites. The incremental sync didn’t fix the problem, and until build 1462 the 72 hour full sync didn’t resolve the problem because the bug triggered again afterwards.
Then you upgraded to build 1462 the bug was no longer present, but Roon still thought you had very few Qobuz albums/tracks, because the incremental sync couldn’t fix that sort of problem. Eventually we finally did a non-incremental sync and everything re-appeared.
I don’t really understand why the IPv6 change appeared to do anything, and also don’t know why the every 72 hour full sync took so long to resolve the problem, but at this point it’s not a high enough priority for me to investigate more instead of a different bug.
Hey Ben, thanks for the explanation, the interaction of the bug with the incremental/full syncing makes sense. I guess I wasn’t clear about the IPv6, I don’t believe it did anything either.

Describe the issue
tracks disappearing
Describe your network setup
fiber -> eero mesh -> ethernet switch -> roon server running on Mac mini
More details: on my home page I started seeing tracks disappearing on batches of 50, about 1 batch per second. This started about 30 minutes ago and continued until it stabilized about 5 minutes ago. I had about 740k tracks and it’s now sitting at 333523. At the same time the number tracks shown in Library->Library maintenance->Clean up library was ramping up at about the same rate. My library is a mix of local files + Qobuz + Tidal. My local drive is fine and a spot check of some local albums seems good. So I’m guessing Roon was removing tons of Qobuz and/or Tidal tracks for some reason.
Possibly your Qobuz account has been compromised? It’s happened to a lot of people recently….
Don’t think so. If I go to Home/Qobuz/My Qobuz, my favorite albums list is huge, as it should be. But my Roon albums view with a focus on Storage Locations/Qobuz Library shows only 47 albums. What’s the cause of that inconsistency?
This looks very much like an issue I reported earlier (ref #H34N2K). The explanation was a bug that caused Roon to believe I have 0 Qobuz favorites, which could not be fixed by the regular incremental sync. Then a full sync that happens at a 72-hour interval fixed things back up. But that was supposedly fixed in build 1462, and I’m running build 1470.

Hi @Vince_Deters,
Thank you for the report. This investigation remains open with development; please allow us a chance to sync internally and we’ll respond as soon as we have a more fruitful update to share.
This morning Roon has slowly started adding tracks back. The number of tracks shown on the homepage is incrementing while the number shown by Library->Library maintenance->Clean up library is decrementing. I guess a full sync is in effect.
