No sound from Roku Ultra LT to LG 2023 tv.
I'm having this same problem. Its with the LG TV, not the ROKU. I know this because not only is the audio from the TV speakers dead but also the ARC port to a sound bar and the digital fiber output port is dead when on ROKU input. When I switch back to Cable, you can see the red lights in the fiber optic come on.
The first time I switched inputs to the ROKU port, a warning came up about sound but it didn't last long enough to really read it. It never came on again.
