I'm trying to connect my surround sound system to my streaming android box for surround sound out of the tv. The home theatre is Coby DVD-925. There is no HDMI port on the home theater. When I play a movie everything is fine as far as the sound and picture. But when I play the box I can see the picture when I change my tv to hdmi input but there's no sound. Also the home theatre only has Aux1 and Aux2 inputs which I don't have on my tv. Please help..thank you in advance.
