Interesting...
Thinking out loud..
So the Chromecast hits the surround first...
I could try one of the other hdmi inputs on the surround, but I'll try maybe some of the TV settings first?
No specific related setting on the TV, but there is a "TV power on control" setting In power management.
I'll give that a shot, then maybe dig out the surround sound manual and see if maybe there is something there if this doesn't work.
Thanks for the idea!
