Description of Issue
I have an issue playing music with my McIntosh C2700 Preamp. Everything was working fine until a couple of months ago when both ROCK and Ropieee has software updates.
I have my Roon Server running on an Intel NUC (ROCK) streaming to a Ropieee endpoint running on a Raspi 4B via WiFi. The Ropieee is connected to the C2700 via USB. I had this setup running fine with no issues for a couple of months, then things stopped working after some software updates. I applied the ROCK and Ropieee updates around the same time, so not sure which might have triggered it.
I can see the Ropieee in my Roon client and select the McIntosh as the target zone. When I select a track to play, it starts to load and then stops abruptly (no audio, but I can see the track info load on a configured display).
I see the following in the Roon Server logs:

@spockfish Has done some investigation from the Ropieee side of things and hasn’t found anything so far.
Things work fine if I connect another DAC to the same Ropieee endpoint. I’ve also setup another Ropieee endpoint with a fresh install and the same thing happens. Has something changed with the “Roon Tested” classification of the McinTosh C2700/DA2?
