Surround sound with soundbar using HDMI ARC
I can't seem to get surround sound on my Roku Stick 4K. I'm trying this with the Roku Fandango At Home app. Here's my setup:
I'm using the Roku Stick 4K connected to one of the HDMI ports on the TV (a new LG OLED G4). I'm using a Sony SA-S350 soundbar connected to the TV on it's HDMI2 port which is an eARC port. The soundbar is ARC compatible.
The sound works when setup like this and the SIMPLINK is working where the TV remote controls the soundbar volume etc.
So far however, I've only been able to get surround using apps built into the TV. I'm not getting surround from the Roku Stick 4K at all. I've tried with the Roku Sound settings set to Auto as well as setting the manual and still no surround.
Any clue what it takes to get surround working? Thanks in advance!
EDIT: Just out of curiosity I did a factory reset of the Roku Stick but that didn't help. Should I be getting surround with this setup? It certainly seems like I should be.
