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?
· 9.20 am PST approx
What are the make and model of the affected audio device(s) and the connection type?
· Apple MacBook Pro built in / optical out to DAC
Describe the issue
Roon sometimes stops after a track has finished when in playlist mode. Albums seem to work fine, It seems to be an issue with changing either bit depth or sample rate between songs in a playlist. Im using the built in apple laptop audio device... optical out into a DAC. I can't pin down if its only one change in depth or rate, or if its ALL changes. Sometimes it seems to cope with the change, sometimes not. It never stops if the next song is the same depth and rate as the previous. So going from 16 to 24 bit can sometimes cause a stop, and going from 44.1k to 48k can sometimes cause a stop.
Describe your network setup
server and library and Roon software all on one laptop
Thank you for your post. The specific handling of a track format change will depend most on whether a) DSP profiles are applied in MUSE and b) the specific firmware of the DAC involved.
Can you please share a screenshot of the Signal Path within Roon for the digital chain with which you’re encountering this symptom?
Do you encounter any error messages within Roon when this occurs? Does playback restart on its own after a short delay?
You can increase the time allotted for hardware to resync to the new sample rate/bit depth during these track transitions by applying a longer resync delay in Settings → Audio → Device Setup (gear icon ) for the relevant Zone.
We’ll pull diagnostic in the meantime to see what we can learn from the RoonServer logs themselves.
Thanks for the reply!
I’m not using anything in MUSE - here’s the signal path (attached)
Playback does not restart on its own… I have to press the play icon (sometimes a few times)
I have noticed that when manually trying to play a track with a different format while the ‘old’ track is playing, I get a message at the bottom of the Roon window that say No Audio Devices are available. then it takes a few seconds to re adjust itself and go back to the one that was previously selected, so maybe this is what’s happening in the background when a playlist tried to go from one format to another.
I have increased the Resync delay tp 500 ms - that sounds like it might help! Ill run it for a day or so and see what happens.
Would it maybe help if I used MUSE to re - upsample everything played to the same depth / rate?
Thankyou!
Hi Matt,
Fellow user here. That is what I would suggest to test things out. Also, you seem to be using the OS Mixer instead of CoreAudio out to the DAC. You might try using CoreAudio.
Let us know how the above goes! We also agree with @Rugby - it would be good to also test out upsampling your tracks, as well as reviewing the CoreAudio driver from the Mac as well.
I have setup MUSE to re sample everything to 44.1 (since the vast majority of my library is at 44.1 anyway) and this seems to have fixed it. I played a varied rate playlist for 4 hours today with no stops! yay!
I also changed the resync time to 500 ms, and was still getting errors. Difficult to tell if this is an issue with Roon though or just how my external DAC copes (or not) with rate changes.
I’ll report back if there are any changes in this, but I think this problem is solved!
Hi @Matt_Robertson2,
Great we’re glad to read that you are now able to use Roon normally. I’ll mark this thread as solved for you. This thread will remain open for a couple of more days in case the problem returns.
