Description of Issue
A constant cycle of failing to sync the clock and giving up. This happens no matter what output is used. DAC itself is not the issue as far as I am aware; works with Foobar, Tidal app, Qobuz app, etc.

Hi, I found a solution to this problem.
In my case, I exchanged my faulty M500 for a new one and Windows and all my other apps were fine with it except Roon. I figured it had something to do with zones configuration.
I made a backup of my Roon DB just in case. Closed my Roon server instance.
I deleted all files (up from a certain date, my original M500 purchase date) from the directory: AppData\Local\RoonServer\Database\Core\< ID >\transport\
Upon restarting Roon, it took it just a tad while longer, but everything worked perfectly as expected.
Thanks for clarifying right away. So sorry about the trouble. If you also do not see the audio devices in Settings → Services, could you please try this:
I do see them, but when I try to initiate playback on one of the devices I get the same error reported in this thread.
From a UX standpoint, Roon behaves as if everything is in order and “start” playing the track. However, the track is skipped without a second of music being played and without any UI indication that there is a problem.
The culprit is my VPN. I’ve been toying with split tunneling to allow Roon’s traffic to be excluded from the VPN. Most of the things worked fine and streaming to my ethernet connected rasberry pi worked fine. However, USB playing didn’t work.
Once I disabled the VPN everything works.
