PCE Duo *no audio* problem

[Artemio]

I just got hold on a Duo, since I've had several Japanese Super CD2 games for a while and wanted to play them on real hardware cause I don't have the CD for my US TG16.

Problem is, that audio is non existant through the A/V cable (it is only a yellow composite connector and a white Audio connector via RCA) and via the headphones it is almost innaudible, connected to the amplifier I can't hear the audio of the game even at the loudest volume... do you guys know any solution for this? Or what would you recommend?

I already tried different amplifiers and TVs, only got one AV cable for teh system, and tried moving it around to check for a faulty one... with no result at all.


I thank in advance any replies....
