I think it is a missed opportunity for full functionality. The bluetooth
delay is caused by missed codec aptx. I did buy transmitter for it but
because the google nest audio misses that codec nothing works.
yes when I unpair them the delay is working as separate speakers. But
when you pair them in stereo the delay is back, Also I got from support
a email that it is not supported that chromecast plays only audio and
not video playback. That is why youtub...
When I setup the speakers seperately I can sync the delay to -150ms,
then there is no delay between chromecast and nest audio. When I pair
them to stereo speaker set I can not adjust the delay. Using the group
delay does not work in this situation.
