Description Of Issue

I have recently installed and set up Roon 1.8 in my home and I’m having issues with one specific device. I have several devices including a NAD M10, KEF LSX, and various Sonos Speakers and Amp. I am ONLY having an issue with the M10.

Some music is displaying weird artifacts, mostly noticeable on softer, quieter music. These artifacts are small static and/or warbling sounds. They seem to be random by song but are reproducible and predictable in any certain song. ie. If they appear at the 23 second mark of a particular track it will always appear at the 23 second mark of that track.

If I play the exact same track, via my library or Tidal, via BluOS or Tidal Direct I do not get any artifacts.

My M10 Audio Device settings in Roon are the default settings and I am not using any DSP processing.

Any advice would be greatly appreciated.

Update. The issue has been resolved. After much troubleshooting, I was forced to Factory Reset the NAD M10. After reset and update process and reinstalling Dirac filters it appears the audio glitches are gone. Neither myself, nor NAD, can make a determination of what the underlying issue was other than “something” in the DSP of the M10 had got out of whack and was conflicting with Roon.
