Mac is running 10.15.1, Roon 1.6, and Poly version 2.0.4
Roon will stream to all devices except my Poly. Songs keep dropping after a few seconds. I’ll either get the “Nothing Playing” text the time duration bar is or “an audio file is loading slowly …”
If Roon is streaming without issue to your other zones, it would appear that the Poly is not working as expected. I would recommend reaching out to Chord Electronics Support for assistance as they will be in the best position to assist you with the Poly diagnostics.
