Need help with outputting audio through TV optical while using receiver
My current setup:
- TV C9
- Denon S720W - connect to TV through HDMI ARC port
- wireless headphone sennheiser RS connect to TV through optical port
What I'm trying to do: when I watch youtube on shield TV that is connected to the AVR for example, I want to switch audio output on TV to optical and have the TV to output audio to the headphone (currently it outputs to TV internal speakers).
I could get it work with the old C6 ie use optical for headphone, HDMI ARC for AVR speakers, but somehow it isn't working with the new TV, the only temp solution I can come up with is to turn off the AVR whenever I want to use the headphone.
I'm suspecting it may have something to do with TV setup so not sure if it is the right place to ask, but does anyone have any idea on how to address this?
