I am adding to the chorus of struggles with the 218s and Roon. I will be updating the firmware tonight (hopefully) if I can secure a Windows machine.

My 218s have been struggling to play Tidal as a group of 3. I did all the tricks the Roon team has suggested. I have had ticket open with them for about two months now. My last attempt was to ungroup the 218s and run two sets of DSP320s from one 218. It ran nonstop for about a week (about 100 continuous hours). Today, it won't make it through one song. My Roon Ready endpoints are rock solid. The Roon Tested, Sooloos based endpoints in the 218s have been problematic. The next step is to get into more detail with my network.

I'll report back after the updates go through.

Regards,
Bill
