I just checked the Roon forum, where a DSJr. owner reported the Bridge II “Uncertified” problem here.
Roon’s Chief Technology Officer Brian Luczkiewicz responded just ten hours ago as follows here:
It's because the device was momentarily identifying itself to Roon as "CDMCM-210" instead of its real name.
I think this sometimes happens after firmware updates of these devices. Maybe something to take up with PS Audio.
So PS Audio suggests we check with Roon while Roon suggests we check with PS Audio…
I would be grateful if PS Audio and Roon would work together to address this issue. Thanks very much.
