Nov 13, 2017 · So, what was causing the problem? The TV? The Chromecast? I finally zeroed in on the problem when casting from the Movies Anywhere Android app. The Movies Anywhere app allows you to select an audio stream: stereo (2.0) or surround sound (5.1). Most movies will default to streaming using surround sound. Apr 14, 2020 · This home theater surround sound system is a 5.1-channel sound system. It supports Chromecast; thus, you can stream music directly using Chromecast-enabled apps and platforms like Spotify, Pandora, and iHeartRadio. The VIZIO SB36512-F6B also comes with a powerful subwoofer that delivers rumbling bass for all your audio needs.
I am using gen one chromecast plugged into an NAD 747 receiver (configured with 5.1). (core is linux). Multichannel material appears to be downmixed to 2.0. Regards Stuart.
