Description Of Issue
TIMELINE OF THIS ISSUE:
Also reported approx 1.5 year ago, using another PC and setup. Also at that time an audio example of the error was provided. At that time, no feedback was received from Roon development, so we thought the error was silently fixed. As it seems, it was ignored, and we corrected the error per coincidence, i.e. by defining exclusive mode for audio output devices.

Please, this time, and as we spend some time creating this report, grant feedback and acknowledge the problem (or advice our wrong use of Roon).
When a Roon output device (e.g. the two examples above) is set in non-exclusive mode, a severe degradation of audio quality is the result. It is a kind of “ringing” that is immediately audible.
The linked wav file demonstrates how Tidal plays perfect (first half), while Roon in non-exclusive mode has the ringing error (second half).
The track is “She - Harry Connick jr”. This is an error with only Roon, playing any track, but no other players has the same error. It is only present in Roon non-exclusive mode (for the audio device selected).
I will be happy to contribute with further info as requested.
