Bose 700 Soundbar not connecting to Spectrum Cable Box
I have a new Bose 700 Soundbar attached via HDMI-ARC to a new Samsung Q70 TV. The TV is connected via HDMI to a Spectrum201 cable box (Humax).
I can only control the sound/on-off on the Soundbar using the Soundbar Remote.
I have to change the channels or use the guide via the Spectrum remote.
I have configured the Bose Music App such that the cable box, TV, and bose universal remote are all referenced in the UNIVERSAL REMOTE section in Settings.
How can I complete the setup so that I can control everything from the Bose 700 Universal Remote?
Thanks in advance,
