I have an av receiver that I cast Pandora and other streaming audio services to via Google Home so I can listen on speakers wired to the receiver. I want to play my roku tv audio through this av receiver and out to my speakers, but don't want to wire audio out from roku tv to the receiver. Wish there was a simple cast button in the roku app that would allow this. Any ideas?
Also interested in broadcasting Roku audio to Wifi speakers. Did you figure this out?
