For the best possible display and audio performance, do I connect my Roku Ultra to my soundbar or to my TV? My soundbar is connected by a certified HDMI 2.1 cable to the tv through a single eARC connection.
It depends on how you configured it. Does all of your TV audio output go through the sound bar? Then you should be able to connect to the TV and let the TV output the audio to the sound bar.

Yes, I am using the soundbar for all audio output. That is how I have it set up (connecting Roku Ultra directly to the TV), but I wanted to make sure I was set up for the best performance. Thanks.
