How do I connect/configure sound bar to work with Z10 and tv.

Depends what your Soundbar support and how your Audio should work.

1. Connect your Soundbar with TV (HDMI ARC), set on TV ( Audio Output device and choose External speakers if you want constant Audio over Soundbar), when this works, connect Formuler Box with Soundbar if there is some free HDMI port.

2. Same like 1. but Formuler connected with TV. TV will forward Audio to Soundbar over HDMI ARC.
