Default input on TV

[RogerAR]

I have a QN80A TV with a Samsung Q6T soundbar connected to the eARC port (HDMI 3), cable box on HDMI 1, ROKU on HDMI 2, and Blu-ray on HDMI 4. Every time we turn on the TV, it defaults to the soundbar for input, so we have to manually change the input to the cable box. How can I fix that so that the default input is HDMI 1?

Not possible without disconnecting the soundbar That's what eARC does.

For me this only happens when the Roku is plugged in to an HDMI port on the TV. Doesn't happen when the Roku isn't connected. Currently talking to Roku support. Did you find a solution?
