Forgive me for raising a topic that may well have been addressed elsewhere, but I have been dealing with an issue between Roon and Sonos. I am in the middle of my first year subscription of Roon and liked it enough (so I thought) to purchase the new Roon Nucleus One. When Roon works, it is wonderful. However .... in one of my setups primarly designed to stream music through various rooms as background using various Sonos components including a port, a Roam and a number of Sonos speakers, Roon worked until for reasons I can't understand it inexplicably would lose control of the Sonos devices despite the fact that the devices do show up on Roon's audio section. I have tried to work with both Sonos and Roon -- Sonos tech concluded that the problem likely lay with Roon while acknowledging that it doesn't have a "formal" agreement with Roon. Roon, whose technical service is nigh impossible to navigate and there is never a live person to talk to, Roon always points you to a do-loop of rebooting and rebooting. I want to use Roon over the Sonos app. In my main high fidelity system Roon works perfectly with my Eversolo Streamer and Qutest DAC. I don't know whether it's because in my main location I have almost 1GB of internet where in our more remote summer place (with only Sonos) I have about 400 mbps. Given the almost $150 a year subscription price, it seems reasonable to believe that Roon should be plug and play, especially when it seems to advertise that Sonos products are Sonos ready. I was especially hopeful that Roon would work because Sonos's spring app rollout was such a failure. If anyone has a magic bullet, please share it with me!
