I stream Roon via Apple Airplay and Sonos. I receive an error message "Roon lost control of the audio device" when I attempt to stream using Sonos. My set up is Mac mini as the server, (2) Sonos Fives, Sonos Arc, (2) Sonos Play 1. The problem started several weeks ago after an upgrade of both Roon and MAC OS.
@Menzies is steering you in the right direction with the questions above. I’d also add that it may be worth reviewing your router settings to ensure your Roon devices are jumping between different local subnets. See if you;re able to confirm everything shares the first three IP schemes, for example: 192.168.1.
Thanks @Menzies and @Benjamin for your quick replies and advice.
I stream Roon via wifi in my home. My router/modem has two “channels” (not sure if that is the right word), 2.5 and 5.0. Setting my wifi on 5.0 I only have access to Roon via Airplay. Setting my wifi on 2.5 I am able to stream Roon over Airplay and Sonos. So, that seems to fix everything for me, unless you both have any suggestions. Thanks again! Much appreciate your advice.
