I have the following setup:
LG 49uf6430 4k tv
Roku Premiere+ streaming device
Vizio 36512-F6 soundbar
The Roku is connected to HDMI 3 input on the LG tv. The LG tv and Vizio soundbar are conneted via HDMI ARC.I've noticed the audio on some netflix shows is coming through in stereo. The shows are definitely supposed to available in dolby 5.1. I've tried setting the audio on the Roku to auto detect and dolby digital 5.1, but I can see in the Netflix debug info:
Audio: English [Original] / stereo (PRIMARY)
Any idea what I'm doing wrong? Any help is greatly appreciated.
