I have Roon linked to my Sonos and seem to be encountering an issue.
My main hifi speakers come from an amp which is connected via a Sonos Connect, I have also added a pair on Sonos 1 speakers which are grouped together as a zone from within the Roon iOS app. My issue is that there seems to be a noticeable delay at the start of tracks before the Sonos 1’s kick in and start playing the music, is this a known issue and has anyone got a fix for it?
