I have an LG OLED CX TV with a Sonos Arc. I want to stream Atmos TrueHD movies from my PC however some research suggests that I will need an Nvidia Shield to allow lossless TrueHD Atmos. Without an Nvidia Shield the Sonos Arc downsamples the audio stream and removes the Atmos metadata so it becomes regular Dolby Digital 5.1.
However the Sonos Arc only has a single HDMI connection and the LG CX only has a single eArc HDMI connection. So... would I get lossless Atmos if I connected the eArc port on the TV to the Sonos Arc and then the Nvidia Shield to a separate HDMI port on the TV?
Thank you.
