I just received back (2 days ago) from Roon my repaired (motherboard replaced with all updates), cannot get it to recognize my McIntosh C2700. I responded to the repair email from Roon about this, no answer. Frustrated beyond compare, hours now researching the site when a simple phone call would no doubt make it work. Still no joy!!!
Hello, thanks for responding. The Nucleus+ is hooked to the C2700 via USB cable, network hooked directly to the Nucleuis+. The network is working as the Roon is operating with my NAS and Tidel through my computers speakers, if selected. The zone in another room works with the satellite Sonos speakers if selected. It simply does not recognize the C2700, which it did prior to the Nucleus hardware problem. I tried various sequencing of connection and system start, no impact. I have logged off Roon completely and restart and logged in, no impact.
So, if I understand, Nucleus >USB>C2700. And this configuration, including the same cable was working prior.
I guess the first thing, I’d do, is switch to a basic 7 dollar Amazon USB cable, if the current cable is an expensive one.
Also, I would power the Nucleus and 2700 down. The order of power can be important, like in computers of old, where you needed to turn on the printer first. I would turn on the McIntosh first, so it is up and powered, and then turn on the Nucleus. USB connects can sometimes be a little finicky.
The typical USB-A to USB-B is used for computer printers, so I used the one off my printer which I know is working. Replacing the cable and going through the start sequence had no impact, still does not recognize the C2700
Use a device you have control over instead of the Nucleus+, using the same USB cable to connect to the C2700. Use that to try and playback music to the C2700. Refer to your manual if necessary (pages 27 + 28 I think).
