I have to ask this question again. Why is it the performance of Sonos in playing FLAC files has waned over the last couple of years since Sonos preoccupation with being all things to everyone i.e. streaming from every possible source, 5.1 etc. Despite having the matrix I have attached speakers drop out especially one side of stereo pairs. Whenever I skip to the next track speakers drop out and slowly synch up again. Does not happen on MP3s with their lower bitrate. Those of us who were early adopters can remember that Sonos was supposed to have the ability to play 32 speakers with multiple music streams in different rooms. The S2 app takes an age to load on a fast laptop. Changing volume settings can now have a delay as others mentioned. Has some of the memory capacity that used to be available been used for the new features. Don't forget the original system was just designed to play music from local sources and a bit of Internet Radio. Perceived reliability has really begun to suffer as witnessed by a lot of disillusioned contributers on this site. I may sound crass to say this but if I could go back about 30 upgrades to the old blue controller I would do so. Sonos is taking my system in a direction I appear to have little or no control over.
