When trying to connect to my music files on my remote iMac, the L.R. Sonos connect won't start and I get the dreaded unable to connect to iMac. If I first start the music in the kitchen..., and then group the kitchen's speakers to the L.R. speakers, it works fine. If I then remove the kitchen speakers from the group, the L.R. cuts out and the dreaded unable to connect displays. If I start the L.R. speakers with say spotify or pandora, it works perfectly on its own. This just happens to the L.R. speakers when trying to access my files on the remote iMac.
