I have a Samsung Smart TV and I don't know what else to do so that the Netflix audio can be heard through an external speaker that I have. I am using an optical cable and a bluetooth transmitter since the TV does not have the ability to transmit signal in this way. I have verified the audio settings on Netflix and I select the standard audio and I achieve nothing. I have also selected optical audio output on the TV and there is no result either. What I don't understand is why the audio from YouTube, Spotify and Pandora are heard but the audio from Netflix and Amazon Prime not. Please someone tell me what I can do. thanks in advance.
