bin's and iso's doesnt have sound ?

hi guys .. wahh today i'm really active in this forum since i registered it . the reply was fast incredible !!!

anyway .. after trying to make ISOz and BINz on my HArddrive .. when i run it using ePSXe .. i found that when MDEC is playing .. no sound came out .. at first i tought it was sound plugin problem but when i put the original cd and play using cd .. the sound came on MDEC movies ... i wonder there's something wrong with my CD to ISO/BIN procedure :

i use ADPRIX ISO BUilt

thanks
