I am new to the AVS forum and really did not know where to put this post. I recently purchased a Sony NX810 tv along with a home theater system that came with an Onkyo HT-R690 receiver. My issue is with sending sound from the TV to the surround sound. I am new to the home theater world but have learned a little bit from browsing the forums. I absolutely hate the manuals that came with my TV and home theater system. They are not too in depth. I have enabled ARC on my Onkyo and have connected a monster 1000 speed hdmi cable from the HDMI out of the receiver to the HDMI 1 of the Sony TV. HDMI 1 on my TV supports ARC. When I turn the TV on, the receiver turns on also and the TV displays a message stating it is using the external audio speakers. There is no sound coming out of the external speakers. There is not many settings to really change on the receiver or the TV. Any other suggestions for troubleshooting or am I missing something?
