I replaced a microRendu with an ultraRendu, leaving everything else the same. Now get the message that Roon can't find HQplayer. Roon found the ultraRendu immediately and opened a box to name it. I typed in ultraRendu instead of living room -- which may have been the name of the microRendu. Could that be the problem? If not how do I fix it? I did also replaced the CIA power supply with an UpTone LPS-1.2, but surely that's irrelevant.
