I’m having a similar issue. My “roon endpoints” were grouped and I was getting errors trying to play any of them. I ungrouped them and found that the others work just fine. Only the Microrendu doesn’t work.
Here’s my setup:
Roon Core: Mac Mini 2.3 Ghz quad core i7 with 16mb or RAM
Networking: Asus RT-AC87R router with Spectrum 400MB connection. Zyzel Powerline adaptors are used to connect the router to MacMini and to MicroRendu.
Audio Devices (Main HT): MacMini is connected via USB to Peachtree 24/196 converter to optical which feeds Cary Cinema 12 PrePro (DAC in the Processor)
Audio Devices (Bedroom): Sonore Microrendu connected via ethernet to Zyzel Powerline adaptor. MicroRendu is connected via USB directly to Lyngdorf TDAI 2170 (internal DAC in Lyngdorf)
Audio Devices (Office): PC running Roon client connected to Peachtree M24 via USB
Audio Devices (Kitchen/Dining Room/Living Room/Bedroom): Chromecast devices that are grouped.
Library: 8.69GB Library is on Drobo Mini connected via firewire to MacMini. Tidal subscriptions as well.
This was working fine until a few days ago and I’m not aware of any software updates that have been done. Everything else seems to be working fine. I can still stream to chromecast devices and I can play music everywhere EXCEPT to my microrendu/lyngdorf. I can still stream music to the lyngdorf via chromecast so clearly it’s not a networking issue between the devices.
I’ve attempted multiple restarts of the MacMini, Roon, and the Microrendu. I even did a firmware upgrade on the Lyngdorf while I was at it.
When trying to stream to the MR/Lyngdorf it looks as if it’s trying to connect, then moves on the next track.
Please advise if I need to put this in a separate thread.
