Any off you have the same Problem that surround sound is out off sync? Stereo is fine, everything else is just crap. I tried almost every solution and chatted with Google. No Fix. Meanwhile on the Fire TV stick everything works fine. Shame on you Goolge.
Had same problem. Went to sound bar and reset sound bar and it started working. Have to reset sound bar every now and then when it stops working. I don’t know if you are using sound bar but it worked for me. Good luck.
