    This is likely a very noob question, but I would really appreciate your help! 🙂

    I am wondering if I actually need to input audio into the OSSC for it to be in sync with the video coming from it. I am using an Extron crosspoint and it would be much simpler to send all audio sources directly from the extron to my speakers, rather than passing it into the OSSC first.

    I plan on doing this for all video / audio sources (SCART, YPbPr, VGA) instead of sending the audio to their respective inputs on the OSSC.
    Is there any delay or desyncs associated with doing this?

    Thank you! 🙂


    I suppose it depends on what you have downstream of the OSSC, if any of that is introducing lag. The OSSC won’t add any perceivable delay.

    In my case, my home theater receiver has several HDMI inputs, so, for analogue audio, since I have both SCART and Component inputs populated and I want them switched, I run that audio into my OSSC.

    Unfortunately, for my consoles with digital audio (PS2, Xbox), I have to route that audio directly from my component switch to my home theater receiver, and then additionally switch TX Mode from HDMI to DVI in order to get the OSSC to stop sending an audio signal so my receiver will correctly fall back from HDMI audio to TOSLINK.
