My Question or Issue

When casting to a group of speakers, all work fine except from nvidia shield (android tv), which lags. If only casting to the nvidia shield (android tv), the sound doenst lag.

Only happens when its part of a speaker group in google home. 

It didnt use to lag, i have had it grouped for over a year without issues.

Anyone with similar issue that has solved it?

Best regards
