Use Chromecast connected to A/V receiver without TV on
I have the Sony STR-KS370 as my receiver with my Chromecast connected one of the HDMI ports. When I get home, I love to throw on some music to help get me into relax mode but I always have to turn on my TV to trigger the Chromecast to wake up. Is there a way for my receiver only to wake the Chromecast from sleep? I can get my way around a basic A/V situation, but I'm not heavily versed.
