There are ways of making it work but, in the end, I bought a Bluesound Node 2i to ensure gapless playback of local files and relegated my CCA to my bedroom system. If you play music through the Google Home app well the app can play gapless, but I think I read somewhere that it transcodes the audio to mp3 first. There's the Hi-Fi cast app as well which can do gapless. But like I say, for peace of mind/end the frustration I just bought a Bluesound Node 2i to be done with it.
