Description of Issue
System has been fine for over a year. Now, when playing iTunes library through Roon, everything is normal when using the one zone powered by the M33. When I add other zones, all powered by the CI 580/CI 16-60 combo, music is out of sync with M33, and zones powered by CI combo are out of sync with each other. Also, songs get started then pause and jump to the next song and that repeats. If the system makes it to the end of the song, it often stops playing before the next song starts. Roon also losing control of device. Same problems if I run the CI combo independent of the M33. All zones powered by CI 580/CI 16-60 are unusable at this point. I don’t have these problems when using the Bluesound app to play radio.
I do find it a bit suspicious that blueos did a firmware update that lost roon if you did a factory reset, then did another update and then blame roon for lost synching.
Often the companies are talking at a level above front line support so probably best to wait and see.
I discovered a clumsy workaround for the moment. If you start playing the group in Roon (which will lose sync) stop play in Roon then switch to BluOS controller and click the Roon Ready icon on the left and initiate play in BluOS the sync issue is gone. Switch to Roon and you’ll see that the progress bar in Roon indicates it’s playing and all DSP is working.
Something clearly amiss. I’ve posted on the Bluesound forum as well.
EDIT: Now it appears all I need to do is select Roon Ready in BluOS and then play in Roon and sync is fine.
I opened a support ticket with Bluesound regarding the out-of-sync issue. After some back-and-forth checking linkup id’s etc they claim the problem lies with Roon. I’m not convinced as the issue only arose after the last Bluesound firmware update.
Thank you for your undue demonstration of patience while we worked through the queue to reach your message. We’re admittedly quite behind but working diligently to catch up.
The symptoms you’ve described might be the result of a clock assignment issue or a network stability issue between the physical location of these Zones. Roon losing control of the audio device corroborates the second possibility. A few questions might help us pin down the problem here:
When you mention ethernet connections in your Setup Details, do you mean to say the NAD CI 16-60 is connected via the LAN/ethernet input, wired directly to either the primary router or the unmanaged switch?
Can you please provide screenshots of the Device Setup page in Roon → Settings → Audio for the group and individual Zones which are having issues? Is the Resync Delay set to a value greater than 3ms?
Do you have any DRM on this iTunes content? Another way of asking: if these are pre-Apple Music iTunes downloads (older than about 2009), there’s a chance some files are still protected, which might explain certain skipping. It’s certainly not underpinning your problem here.
Lastly, we’ve attempted to pull more precise RoonReady logging from your account, but it appears your Core is offline. When you have a chance, please open Roon for at least an hour so we can gain secure access to verbose logging from Roon’s communication with the affected endpoints during playback.
Thank you for the reply Wes. Yes the issue is ongoing with grouped endpoints. It occurred after the last Bluesound firmware update. It does not happen on in the BluOS Controller app.
If I keep both Roon and BluOS open I can start playback in Roon then stop playback, switch to BluOS and select Roon Ready and restart playback from BluOS which restores sync most of the time. Others on the Bluesound forum have commented on the same issue.
Connor, thanks for your reply. The Core is back online.
Yes, all devices are connected to an unmanaged switch (see photo). Connections to switch are: ethernet from wall, M33, CI 16-60, CI 580, iMAC, eero, TV. Photo of device set up page attached. All Resync Delays are set to zero. I do have purchased music from before 2009, but none are labeled as protected, only purchased AAC or matched AAC.
To describe the problem further, I can turn on Roon and run multiple zones for a few songs without syncing problems, but then the problems start, usually at the beginning of a song is when it goes out of sync. Then it may start jumping songs as previously described. There are no problems when only running the M33.
I have this issue too. Do you just want us to report in this thread the date and time when the out-of-sync problem occurs or is there another way of submitting data?
It appears to be ok, I had some feedback from BluOS as well and I think there was a further update.
The first day after there was occasional sync issues but none since.
