Roon “silently” plays Qobuz intermittently

I opened this question on the Support topic, but I’m not getting any responses… so I thought I’d ask in the NAS discussion as well to see if I could get any suggestions.

Roon "silently" plays Qobuz intermittently

Roon Core Machine Roon 2.0 build 1311 running on QNAP TS-873A QTS 5.1.2.2533 Networking Gear & Setup Details HP ProCurve switches Raspberry Pi 4B, RoPieee 2023.09 (1117), Allo DigiOne HAT Connected Audio Devices Denon X2000, SPDIF Number of Tracks in Library 7500 tracks Description of Issue Have a Qobuz subscription, playing CD-quality audio. Also have my local library ripped as either FLAC or MP3 192 or 320. I often set up a few tracks in the queue, mixed from local library and…

I have current build of Roon running on QNAP TS-873A on QTS 5.1.4. My usual playback is onto a Ropieee instance with an Allo HAT.

While I’m playing music, sometimes a Qobuz track will start playing, I see the progress indicator moving, but no sound output. If I skip forward to a local file, that will play fine, and usually a Qobuz track will play fine after that for awhile, until the whole thing plays out again. I find no specific tracks cause this. I’ve tried installing a static-linked ffmpeg as well, but that doesn’t help (may actually make it worse).

Anyone have any suggestions on anything I can try to debug the issue? I could move off the NAS, but I kinda like having it run there. Thanks in advance.

I’ve observed the same thing with Qobuz. Most of the lag issues can be solved by restarting my ROCK. If that doesn’t work, and things are still being laggy, I’ll adjust my DSP sample rate conversion settings. Most days I like to upscale as much as possible (power of 2), but that definitely can slow everything down on my system - 7th gen i3 NUC running ROCK. If I change that to just Max PCM rate, things are generally all good.

Good luck. Hope you find a solution. I’d reboot and adjust and that will likely help.

Not sure what you mean by “lag”… you mean a delay starting playback of the track? How long a delay? When I experience this it is a delay of indeterminate length - meaning it doesn’t start. I need to intervene to select a different track in the queue.

I’ve done reboots, but it doesn’t solve the issue. I’ve not changed any DSP settings.

There is a file “RoonOnNAS.log.txt” in the database folder that includes entries like belw. Is this relevant?

I was able to solve this issue based on this answer:

Sounds like the dac in the Denon maybe tripping up at sample rate changes. Try to establish if this only happens on certain tracks of a certain sample rate and bit depth. Try upsampling content to the max rate the device supports which is 192/24 and see if it all plays ball.
