Your image is the issue. Something is wrong with it. There are two different versions of Ys IV too, so that could also be the issue. You need to get a nice clean image, that has not been patched, and apply the patch to that. For whatever reason, yours is not playing redbook audio. If you have burned before without issue, then it has to be the image source. I ripped my own game and applied the patch with no issue, and it plays in my Duo.
