Description of Issue

I suddenly cannot enable my NAD C389 in Roon. This was preceded by Roon not playing numerous files in my database.

Hello @Wade_Davis

Thank you for reaching Roon support.

Due to recent changes on the NAD side, some parts of the devices are identified incorrectly. We have reached out to our partners team to resolve the issue.

So in the meantime NAD products do not function as Roon endpoints?

[Wade_Davis]

NAD has a different explanation. And since the last software update for NAD’s BluOS occurred on August 5 and this problem did not occur until August 21, I am inclined to believe this is a Roon issue, not an NAD issue.

Hello Wade,

Thank you for contacting the BluOS Support Crew.

The NAD C389 is officially Roon Ready, so it should normally appear as a certified endpoint in Roon. Occasionally, Roon may temporarily list a device as “Uncertified” if their database and the player fall out of sync.
Please try the following steps first:

1. Power cycle your C389, your Roon Core, and your network router.
2. In the BluOS Controller App, confirm your C389 is on the latest firmware (Settings > Player > Upgrade).

If the issue persists and the C389 still appears as “Uncertified” in Roon, this will need to be addressed directly by Roon Labs, as certification and endpoint authorization are handled on their side.

Kind regards,
Vishnu M

Hello @Wade_Davis

Thank you for the update.

We’ve seen multiple reports with similar devices, and we are currently updating our database to restore Roon Ready functionality. The root cause is that the manufacturer changed the device’s advertisement settings in their firmware.

I’ve explained the details here:

NAD C399 Roon Ready Audio Device will not enable

Hello @Heinz_Schweitzer, Thank you for contacting Roon Support and for your valuable feedback. I have enabled and reviewed the diagnostic data for your account, and it appears that the device ID has changed since the last update, as we can see that the previous model name does not contain spaces, and now this device, due to additional space in name is not recognized by Roon as Roon Ready. 07/08 20:11:10 [Local 07/08 20:11:10] Info: [raat] Initializing RoonReady Device 07/08 20:11:10 [Local 07/…

Our partner team will be updating the database as soon as possible, and once that’s complete, you should be able to enjoy listening again without issue.
