I have my Xbox 360, DVD player, and Satellite Receiver all connected via HDMI to my stereos receiver. From the receiver I have one output cable going into the TV via HDMI. The problem I'm having is getting surround sound when using the Smart TV apps, specifically plex. I have set the TV to output using the "External Speakers" instead of "Internal Speakers". I believe this uses "SPDIF", or at least that is the only option available when I have once I switch to External Speakers.
I am unable to switch back to Internal Speakers once I switch to External Speakers and turn on the receiver. Therefore it seems like the TV is aware when the receiver is on and when it is off. I'm wondering how I even know what channel my receiver is suppose to be on, or if the audio is being correctly sent back from my TV.
Could anyone provide me some information on what I am doing wrong, or how I should be doing this?
