I have the LG CX77 and a Sonos arc connetec. I have Chromecast on HDMI 1.
When I watch a movie on Netflix using Chromecast - I get great sound through the arc (surround).
But when watching am movie using the built in Netflix App or watching cable - I dont get good sound. Is there a way to configure the sound to be better / consistent with my Chromecast expereince?
