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 Qobuz. All seems to work fine, until for unknown reason a Qobuz track starts to play… I can see the progress indicator showing the track playing and advancing, but no sound. Restarting playback on that track doesn’t get the sound… but if I play a track from local library, then try the Qobuz track again, it works fine. And, it continues to work until, arbitrarily, it stops again.
How can I figure out what has gone wrong? I’ve restarted the Core and the NAS, I’ve tried with and without a local static-linked ffmpeg. This has also continued to happen across many releases of Roon and Ropieee, I don’t know exactly when it started happening.
Thanks for your patience while our team works through each thread!
As of right now, there isn’t a way to skip or block AAC files from Qobuz through Roon. Your best bet would be to ask Qobuz directly if there’s a way to restrict playback to FLAC on an account basis.
You could also see about ruling your NAS out of the question, and temporarily host Roon Server on your PC.
Unfortunately, I think you don’t understand the problem.
My issue is that the ffmpeg apparently on the QNAP by default has no AAC codec, so some radio stations do not play. I’ve tried to replace the ffmpeg with a current statically-linked version, which fixes that issue. But, randomly, Roon starts playing a track from Qobuz, and no sound comes out.
Restarting playback on that song doesn’t help. But, playing a local library track, then going back to Qobuz works.
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.
Thanks for the reply. So far it’s just been FLAC at 44.1 16 bit music… Not expecting any real sample rate changes, but will look for a pattern. As noted, the same item from Qobuz usually plays fine, except when it randomly doesn’t.
I turned on sample rate conversion in MUSE for 192/44.1. Don’t think there’s any DAC-related settings in the Ropieee or Denon ends… Playing with that to see if that changes anything.
Thanks for this suggestion of enabling sample rate conversion. Not sure if it was tripping up the Denon, or the Allo Digione HAT, but since adding this I’ve not experienced the issue. Even moved to the custom FFMPEG to fix the AAC support issue on my NAS.
