Sending a quick update…I gave up on Miracast with the Pixel…don’t waste your time.
Casting on a Moto G7 Plus worked OK, but it was flakey. Sometimes it would connect as audio only, other times it would have video and no sound. In this case, we would have to do a dance with bluetooth and the soundbar. Depending on which was connected first, one might kick the other off.
Needless to say, it was NOT an Apple TV kind of experience…until I tried a OnePlus 7T (the last 4G only OP series). Now, casting works very similar to Apple TV, with an extra step of accepting the connection on the TV. Sound works. Video works. It’s a beautiful thing.
I understand why the Pixel did not work (they are forcing you to use Chromecast). As for the Moto being flakey vs the OnePlus working great, I am leaning towards hardware. The OP7T has the SnapDragon 855+, which I think the “+” was focused on video for games.
HTH!
