I've had a recent issue come up with DTS Play-FI/Spotify Connect integration. I'm using the latest versions of the Spotify and DTS Play-Fi apps (and latest version of iOS). If I create a Spotify Speaker Group in my DTS app, I can see it in Spotify all and even connect to it (the speaker lights flash when I play/pause/change volume etc). But, there's no sound from any of the speakers. On the flip-side, if I delete the Spotify Speaker Group in my DTS app, I can go into Spotify and connect to individual Play-Fi speakers and everything works fine. I just can't get Spotify to play to a group of Play-Fi speakers. This has just started in the last couple of days. I've tried deleting and re-installing both apps, but no luck. Any ideas?
