I use Sonos streaming from my core (laptop and roon Win10 desktop app) sounds great. I don’t have the acumen to engage with the above sound variables.
I did find this: Why "Roon Ready" or "Roon Tested"?
However, I am curious as to the differential between audio output channels’ “roon tested” and 'Other network devices"? I’d think Sonos would be roon tested by now.
