I have read about 20 or so posts on surround sound, I have read the FAQs, I have google and binged Tablo surround sound. My problem seems simple, but I have not found an answer. I use only my PC to watch college and NFL football games using Tablo for OTA games (FOX, ABC and NBC). When I select surround sound, then record a game (like green bay at chicago thursday night), I get no sound. I know that game was broadcast in dolby 5.1. When I watched live on my TV, I clearly had two front speakers, two rear surround speakers, announcers on the center speaker, and a subwoofer channel that came through OK. When I watched the game live on Tablo using my PC, NO sound. When I watched the Tablo recording on my PC, NO sound. I tried watching the game using my TV with fire stick, NO sound. When I switch OFF the surround sound check box, I get 2 channel sound. I can watch DVDs on my PC, and I get clear 5.1 surround sound with voices on center speaker and a great subwoofer. It is NOT a problem with my PC sound or my audio system (Asus Z270E and Logitech Z506). I have tried deleting the Tablo device from my PC, then reconnect and resync. No luck. I have tried resetting the tablo with the blue button in the back, I have tried removing power for 30 seconds, then reinstalling power. No luck. What can I do to get 5.1 on my Tablo?
