      Hello! I am using the AV4 port of the OSSC Pro to downscale my hdmi digital consoles to output 480p for my CRT and add fake scanlines. However, there is no audio. I have tried setting my consoles to stereo output and that does not help. I am occasionally getting crackling noise. I know audio works on the OSSC pro as my analog consoles are plugged into AV1 and work fine. Although, if that input is selected without a source I do get glitch noises.

      My set up is: Video game consoles > HDMI switch > OSSC Pro > Hdmi to Component transcoder > Audio Video Receiver > CRT

        Make sure the consoles are set manually to output only stereo. It’s possible that they’re outputting 5.1 LPCM or Dolby Digital.

          Taking the converter out of the equation, if you just feed the HDMI out from the OSSC Pro back into a display, do you get sound then?
