I purchased an RGB modded duo-r from ebay (from doujindance) and it works fine, however there is a strange sound problem. Redbook audio and chiptunes sound fine but most sound effects have this strange popping or crackling sound to them. I tried 2 different AV cables and had the same result.
It happens in hucard and cd games. I have heard many stories of the black duo's sound problems but I thought that with the duo-r/rx those problems were eliminated. I recorded the pause sound in dracula-x hopefully this will illustrate the problem because it's kind of hard to explain without hearing it yourself
any ideas or am i just hearing things?? here is a link to the WAV
