Hi, I can play audio regularly when watching tv but when I am watching something on my amazon fire tv stick the video plays but no sound come out of my Bose surroud sound system. I have the fire stick in HDMI input on my tv, the Video/Y cable plugged into the tv and the other end plugged into the Composite Video Out input, the Cable-Sat red and white ends plugged into the Bose box and the other red and white ends plugged into Audio Out input in my regular tv box
