I just bought a blu ray player and my stereo acts as my surround sound. The stereo is almost like new but it doesn't have HDMI or coaxial ports. How do I hook up my stereo to the blu ray without those ports?
If the Bluray has two audio out ports, typically RED and WHITE, use those.
Otherwise you hope the TV down converts the HDMI audio portion for you and makes it available in its (TV) analog audio ports, then you can hook up your stereo there.
