Thanks!
Interesting there was no option in Roon to adjust the max sample rate under advanced settings for this dongle.
(One thing to note is that when I clicked the “advanced settings” tab, nothing happened. It took me longest time to figure out to scroll down to see the actual new settings.!)
With a lot of experimentation I found out that the following settings worked for this Dongle in Windows:
Clock master: default
Channel layout: 7.1
Stereo/mono content as 7.1: yes
Multichannel mixing: either setting works (I don’t know what this setting actually does).
I also have it on non-exclusive mode so that the software that comes with the dongle can do EQ, etc…
Interestingly, the Advanced options are very different when the dongle is connected directly to Mac.
