Describe the issue
Hi. Still having random stops with roon playback of local music files. Not sure if this ALSO happens with streaming because i dont use streaming. In order to mix it up, recently moved Roon server onto a new mac mini, and converted all library to FLAC. So its all the same format now (although some different sample rates etc). After a few hours of a playlist playback, roon just stopped. Please see screenshot for approx time. I thought that the issue (previously) may have been running roon server and the end point on the same laptop, but now I have seperated the two and I still have the same issue. The commonaility is that the end point in both cases which stops is a 2015 intel macbook pro. However, this is the end point that kinda needs to work! Please help! :) Can you see what happens on your side around the time of the stop?
Describe your network setup
mac mini (server) and laptop (end point) both connected to router via ethernet
Thanks for reaching out. I enabled diagnostics for your devices and I do see the playback abruptly stopping, though it is not entirely clear as to why, though there do appear to be quite a few network disconnections logged in both your Roon Server and the Roon Remote. What is the model/manufacturer of your router? Is it using the latest firmware?
We’ve discussed this with our senior QA and development teams. The team is investigating some possibilities here and, as soon as that investigation is complete, we’ll be sure to follow up ASAP.
You have our apologies for the trouble here, and we’ve greatly appreciated your patience as we continue investigating this tricky issue. We’ll be in touch as soon as we can.
Thank you for the information. The R&D and QA teams are actively working to find the root cause of this issue. We will keep you informed of any updates. If the topic is closed, we will reopen it.
Does the issue happen with local library music, streaming service music, or both?
· *Only local library *music is affected.
Where is your local content stored?
· On the same machine where RoonServer is running, internal drive
Please try playing content of a lower sample rate (44.1kHz or 48kHz), does this work as expected?
· No, lower sample rates are still affected
Do you have an approximate timestamp of when the issue last occurred?
· please see above support ticket
What are the make and model of the affected audio device(s) and the connection type?
· see ticket
Describe the issue
Hi - can you re open ticket "Random Stops during Local Playback on 2015 Intel MacBook Pro Endpoint (ref#M4A1KC)" as you said you would please? This issue is still happening and I have not heard any news from support. Please help!
No other software running, it only seems to happen when using the 2015 Mac/Cambridge amp as the end point. I have roon end points on a Fiio dap and on another MacBook Pro (m1) and they seem fine. Roon server is now running on a Mac mini, but I still get the problems with the 2015 Mac/Cambridge combo end point.
I suspect it might be something to do with the Cambridge amp trying to change the sample rate between songs in a playlist, and failing somehow, and then Roon gets confused? I was experimenting with re-sampling everything to 48K in Roon and I don’t think I had any issues when I did that although it’s not ideal.
I’m currently experimenting with using an external RME dac on the 2015 Mac end point and so far it seems to be behave fine…. I.e. taking the Cambridge amp Dac out of the equation, and any potential sample rate change/reclocking issues
That’s an excellent theory - while our team continues to investigate further on our end, I’d be curious to see if adjusting the Resync Delay option helps at all. Here’s more info on this:
Let me know if that changes any of the behavior - thank you!
We wanted to reach back out to see if changing the Resync Delay to a higher integer in Device Setup (for the Cambridge) had any effect.
At your convenience, please let us know the last time (approximate timestamp or the track that was playing) you experienced a dropout with this Zone. We’ll examine the event in diagnostic logging.
Hi, you know what, I kinda gave up with the laptop optical out > Cambridge, I tried resync delay, resampling everything to the same fs, and nothing seemed to make it work reliably. It must be something to do with the laptop optical out / Cambridge combo because if I use Roon with either my RME UFX (analogue into the Cambridge amp rather than digital) or just use the headphone out of the laptop, it seems to run fine! thanks
Thanks for the update. Since the other zones are working as expected, it does appear to be limitd to the optical and/or Cambridge zone. I assume you’ve tried a different optical cable and have updated drivers?
