Title: duo-r sound issue
Post by: Cyborc on April 07, 2009, 12:47:28 PM
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  http://members.cox.net/mevans1182/draculax.wav

Welcome Cyborc!  :clap:

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  :D

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!

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.
