I ordered the HD retrovision cable with ps1 adapter to hook up my ps1 with the ossc. I’ve noticed that the ossc only has 3 inputs for component. Further, I’ve noticed that the Samsung adapter, to hook component directly to my tv, also only has 3 inputs. Am I missing something obvious here? Both these devices seem to be missing the audio inputs. Component cables have 5 outputs but both the ossc and my tv provide 3 inputs. How am I meant to input audio? There must be an obvious answer to this I’m missing.
