The technical support team is looking into your case. We’ll respond in more detail once we have more information available.
An initial pass through some automated diagnostic information from your account suggests this might in fact be the cause of a faulty USB cable. In the meantime, I recommend you try swapping out a different cable (any USB cable will do). Even if this cable has worked in other settings or with other devices, it’s worth removing it as a variable, just in case. We’ll keep an eye out for your response.
Find the folders named “RoonServer” and “RAATServer”
Rename the “Roon” folder to “RoonServer_old” and “RAATServer” folder to “RAATServer_old”
Restart the RoonServer in the WebUI to generate a new RAATServer and RoonServer database
Next, power cycle all the hardware involved (network gear, Core, Remotes, and DAC). While tedious, it may resolve the issue, and if the issue is indeed at the hardware/kernel level, this step will clean noise from logs to streamline our investigation.
I deleted the Roon app from my phone and from my MBP. After reinstalling I was at least able to connect to Nucleus again, however, the initial issue still remains. Roon is not recognizing the Border Patrol DAC that was working prior to the latest update.
I was able to connect an Audioquest DAC directly to the Nucleus on a USB port with no issues. Roon recognizes it and I’m able to play music to a pair of headphones. Conversely, I’m able to connect another source via USB to the BP DAC and it works fine and plays music to my main system. So it seems both units are working but not together??
I keep troubleshooting this issue as it continues to be a problem. I was able to power cycle Nucleus and plug in the AQ DragonFly dac today. Roon recognized it as an audio source and it’s working today. I’m cautious because previously it only worked for a day and then it continued to not be recognized.
However the main issue is the BP DAC continues to not be recognized as an audio source via Roon after the last update. Also stated previously, this DAC continues to work with no issues when it’s not connected to Nucleus.
Do you have any updates that might help me in my attempts to resolve this issue?
The Border Patrol DAC connected directly to the Nucleus USB ports continue to not be recognized via Roon as an audio source. This coincides with the latest update from a week ago. The DAC and Nucleus otherwise work as intended. It has now been a week since any follow-up from Roon. Please, can someone help me troubleshoot this issue? Is there anything I try to resolve the issue moving forward?
I’ve been in contact with the manufacturer of the Border Patrol DAC regarding this issue. They were able to provide some hardware troubleshooting tips. Swap usb cable, power cycle DAC while everything is connect but these have not resolved the issue.
Can I please get @support regarding my issue. Could this possibly be a USB driver issue with the Nucleus?
