    Greetings, forum. I recently received my OSSC 1.6 (with built-in audio board) in the mail, and I’ve really loved it so far. For getting pixel perfect integer scales of classic games from authentic hardware, the OSSC is simply a godsend. I’ve had a few issues with it, but for most of my consoles it works perfectly and gets me better results than what I could squeeze out of the Framemeister (yes, I have one of those, too).

    One of those issues regards audio from the SNES. I have an RGB-modded SNS101 (Junior/Mini) with a csync SCART cable. I know it’s not the console or the cable because the audio comes through perfectly on my XRGB Mini. Additionally, the AV 1 out on the OSSC also outputs audio when I connect headphones to it. This seems to happen regardless of whether the Audio samplerate on the OSSC is set to 48Khz or 96Khz. I’ve tried mixing the AV1 out with the HDMI footage on my capture card, but then the audio is too loud and frequently clips.

    Do you guys have any ideas about how I could fix this issue so the audio will properly flow through the HDMI out along with the upscaled video? Thank you.

    Sorry, what’s the problem with the SNES exactly? You’re not getting digital audio with it?

    Precisely. I get audio output through the AV1 out jack, but no audio output through the HDMI. My Genesis, RGB-modded N64, and PlayStation all output sound through the HDMI just fine. It’s just my SNES that doesn’t work.

    Are you getting no audio whatsoever or the occasional burst then cutting out or..?

    It’s likely due to NES/SNES clock characteristics – technical explanation here. A mod is under development to fix the issue.

    Alright. I’ll keep my eyes on the forums for a release of the mod in the future. Thanks for your responses!
