How do I get Amazon (or other internet APPS) to play through the Digital Audio Output?
I have tried changing TV settings sound to external speakers with no success.
Digital Audio Output (optical) connected to a DAC and then to Stereo Pre-amp. HDMI in 3 (ARC) connected to BluRay DVD player and HDMI in 1 (STB) connected to cable box. Both will play through the Digital Audio Output to my stereo speakers, even though TV sound settings set to TV speakers.
Internet is wired connection through ethernet through modem from cable company.
