Roku is connected via HDMI 5 port (4K @ 60hz). Sound bar is connected to HDMI 3 (ARC) port.
Audio mode: Auto (DD, DTS) Streaming audio format: Auto Digital output format: Auto
Tested YouTube TV, Netflix, HBO Max, Disney+, Amazon, Apple TV.
So far, my bar’s center channel is ONLY active with Apple TV and HBO Max. Everything else appears to be in stereo.
Also tested my Blu-ray player connected to a different HDMI port. Output via ARC to my bar DOES have the center channel active, so the problem appears to be with the Roku.
Just moved my Roku Ultra 2020 (4800X) from another TV to this one and all apps besides YouTube TV (expected) have correctly functioning surround sound. I also noticed this Roku has slightly different audio options in the settings.
Never figured it out @TomClark. The problem Roku Ultra was moved to my bedroom with just a 40” TV and no proper sound ever since. You are making me curious if it might have received an update that would solve the issue since I made this post forever ago.
Thanks for the reply! I went ahead and signed into the Youtube and Fubotv apps that were preloaded on the lg tv. Plenty of surround there! Really makes me wonder why I'm using a roku with a smart tv. I'm sure the grandkids would laugh at the old guy lol! Take care.
