I apologize about the delay in getting back to you here, QA has analyzed your logs but unfortunately they don’t have any conclusive information about what’s going wrong here yet.
We also spent some time trying to reproduce your issue in our QA lab, but so far we have been not been able to reproduce the symptoms you’re describing.
Obviously, we are keeping this ticket open and continuing to do testing to see if we can understand why your setup seems to be behaving differently then the setups being used in our testing. In the meantime, it would be helpful if you could temporarily run your Roon Core on the Windows machine and confirm whether this issue still occurs. You can do that by:
- Making a backup
- In Settings > General, clicking Disconnect
- Selecting “This PC”
- Logging in and De-authorizing ROCK
- Adding some music and setting up the DAC with the same settings
It might also be worth connecting DACs to the Windows machine, and then confirming whether you’re seeing this issue both with any firewalls off and on. And, if you haven’t already, testing your devices with a new USB cable is a good idea.
Our testing here is still ongoing. I will be sure to update you once QA has a clear sense of next steps. Thanks for your patience here @Dirk-Pitt, we will be in touch once I have more information.
