Description of Issue
I have found two 96kHZ 24bit songs that will not play all the way through when using RAAT from the Nucleus+ to my Atom.
- come on songs by Adrianne Lenker
- Artangels on Art Angels by Grimes
I use Roon with my Atom 99% of the time. I rarely have any issues. However, if I try to play the above two tracks, they always stop mid-track. It took me a while to narrow that down, but that is currently the case. Iām certain itās not a network issue (unless you prove me wrong) because of the consistency of it always stopping for those two tracks, but not others. The other oddity is that the tracks donāt always stop at the same time. Itās generally in the same range, but it can vary.
I have had this issue for several months, maybe even getting close to a year. It is not directly related to the recent firmware updates for both systems - Roon (108 build 882) or Atom (3.8.0.5355). I was hoping the recent firmware updates on both systems would fix this issue, but that didnāt happen.
I attempted to isolate the issue and I do believe it is with RAAT. However, I canāt tell if itās on the Nucleus+ side or Atom side. Initially I was streaming from Roon + Qobuz when having this issue. I eventually purchased the same albums directly from Qobuz. I placed them onto the Nucleus+ internal storage, as well as a USB. I did this to prove the best I could that the tracks Iām testing with are not corrupt.
For independent testing, I used the Qobuz client built directly into the Atom. I also plugged the USB directly into the Atom for additional tests.
Test results with 'come' and 'Artangels' 96kHz 24bit | Source | Transport | Result | |------------------+-----------------------+----------------------| | Qobuz Streaming | Roon RAAT | Stops mid-track | | Internal Storage | Roon RAAT | Stops mid-track | | Qobuz Streaming | Roon Chromecast | Plays complete track | | Internal Storage | Roon Chromecast | Plays complete track | | Qobuz Streaming | Atom Qobuz Client | Plays complete track | | USB | USB plugged into Atom | Plays complete track |
I do have logs capturing the results of my testing, and I can easily recreate the results if needed. Here are relevant portions of the log showing Artangels stopped/paused at 0:24.
