I have the Arc, two Ones for surround and the Sub Gen 3 hooked up to eARC on my Toshiba E9 OLED (surrounds and sub are wireless).
Arc is mounted below the tv. Ones are behind the sectional. The sub is against the wall to the right of the ARC. The TV is in the corner.
The app sees all the speakers. When I turn the sub off in the app the bass sounds noticeably louder. I’m concerned that the Sub has not connected correctly.
