xg1v4 box inputs
My new xg1v4 comcast box does not have audio (red & white) inputs for my surround sound unit but does have an open HDMI input in the back; can I get an audio adaptor to HDMI converter and use that open port for my surround sound? I want surround sound while I am watching comcast programs, my old comcast box had audio inputs but the new box does not.

Doesn't your TV have audio out? Red/white connectors were just left/right anyway. If you want surround you need optical or HDMI connections. You might be able to use HDMI ARC from a different TV input to your surround sound unit.

Optical connections have been around for 30 years or so - hdmi came somewhere around 2002. But the point still stands that you don't get surround sound with the red/white connections. You either need optical or hdmi inputs or you need 6 discrete analog connectors to get surround. If your audio system has more than two speakers it must have those inputs. Or, if you are OK with 2 channels, you may be able to configure your TV headphone output to use line out levels and use an adapter to RCA plugs.
Edit: I guess there was something called Dolby Pro Logic that was used for a surround effect with just two channels of audio before digital systems were invented. You might have one of those.
