I have a Q600b soundbar with a Q90b TV both 2022 models, does anyone know why my soundbar dissapears from my sound select list but will reappear when I switch my HDMI 1 device on which is a Humax Freeview PVR? I connect my Q600b via HDMI ARC. Seems like connectivity between the TV and Soundbar is linked somehow via the HDMI 1 port even though the HDMI ARC port is HDMI 3 on the Q90b TV?
