@rovinggecko’s suggestion is good–the production Meridian firmware still isn’t sharing endpoints nicely with Roon. They have shown signs of working on this problem, but have not made a release yet.
I would also suggest:
- Powering off then on the MS600
- Restarting Roon
in that order.
We’ve found (and reported to Meridian) some bugs in the MS600/MS200/ID40/ID41 firmware that can result in the device crashing. Sometimes it comes back, sometimes it stays gone. We’ve been making detailed bug reports to Meridian and are helping them track this stuff down. They’re working on it.
Because Roon runs on PCs and not on appliances (and PCs can go to sleep, wake up, be on wifi, exhibit a wider range of performance/networking behavior, and so on), the Meridian endpoints are being subject to more adverse conditions than in the Sooloos world. Some longstanding bugs have come to the surface in this transition.
