3. Confirm the proper linkage of both the 8K television and the speaker to the HDMI port, specifically the eARC/ARC port.
4. Configure your 8K television to the mode titled "Use audio system for audio output"

1. In 2 in 1 out mode, ensure connecting both input devices to IN/OUT 1 and IN/OUT 2 ports.
