I've bought a NAD amplifier with integrated google chromecast a couple of months ago. I use Google Home. It worked flawlessly for some time, but then the following problem occurred: when casting an album/playlist via spotify, every second songs starts with at second 2 or so, whereas the third song starts with the first second of song number 2. Patern repeats. Also when casting via laptop btw. When in shuffle, no problem. Also, on laptop, when using crossfade, no problem. IPhone doesn't respond to crossfade when casting however. I've received a new amplifier from the dealer (although they couldn't duplicate the problem - good service!) but no effect.
