I recently upgraded Roon server and most clients to 943 without incident. This was a week after I had rebuilt the server from factory reset in order to replace primary hard drives with larger ones. The day before the problem I had also upgraded from QuTS Hero 184.108.40.2066 to 220.127.116.112. Roon played using .2022 for several hours until it stopped abruptly without warning or any intervention in the interface.
I noticed that Roon (using the client on a Mac) said that it didn’t have an endpoint chosen, which was weird. When I clicked to select one, I noticed that all endpoint references were gone except for HQPlayer. I have two HQPlayer setting in Roon for my Oppo 205 and Oppo HA-2 respectively. Both HQPlayer references were there, but neither of them could play.
In Settings->Audio, no Endpoints showed up at all except HQPlayer. No Apple TVs or Airports I have on the network, none of the Oppo players or their RP4/RoPieeeXL/Roon Bridge companions, not even the physical ports on the QNAP itself. Curiously, the Roon Bridge software on the RP4/RoPieeeXL devices did show up in Settings->About.
So I was completely down with no way to play music and no apparent way out or something that I could point to as something I did. But then I decided to try something. I brought out an old Mac laptop that had an older Roon Client (931) but I told it not to update itself. I went into the Settings->Audio screen and lo and behold, all of the endpoints now showed up. What’s more, they now showed up on all other Roon Clients in my house that weren’t showing endpoints before, including my iPhone and iPad. And music played on all endpoints.
So now i have no idea what happened here or why the older copy of Roon Client helped the Roon Core find the endpoints again. Needless to say, I’m holding off upgrading this one machine in case this happens again. Any ideas?
