Just feed the sound from your TV into your receiver, and then turn your TV sound all the way down to "zero" - then you will just use the receiver as your sound source on all programs - TV,, Netflix, Amazon, etc.
That is what I did and it works great. How you do that will depend on your receiver inputs - could be done with HDMI, rca feeds, or optical digital cord - whatever it will accept.
If you mean Amazon Prime content the answer is yes... But with a caveat. The Wifi range of this TV is the worst of any device in my house. Using built in Wifi 45 feet from my router I was unable to watch Netflix or Amazon Prime. However I bought an external Ethernet Wifi bridge for under $30 that allows me to use the TV's ethernet connection and the bridges wifi connection to stream live content from a variety of sources. It works nicely. Picture and audio are great. Control is responsive. Overall a great experience... Without the bridge..... VERY POOR!
