duo-r sound issue

[Cyborc]

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

Welcome Cyborc! 

So I didn't really hear much in your sound file. Couldn't turn it up too loud though because had a little one sleeping in the same room.

thanks for the welcome 

it might be kind of hard to hear what the problem is unless you crank the sound up. or listen thru headphones. I usually play games with my headphones on so thats how I noticed the sound problem in the first place. I'm wondering if it might be electrical or RF interference because sometimes when I play a cd game, during a quiet point I can hear the sound of the cd drive in my headphones!

can u notice from TV speakers?

[Cyborc]

yes but only if I really crank the speakers up. most of the time the clicking or popping or whatever is drowned out by the music but sometimes it isn't. its kinda annoying but not a dealbreaker by any means.
