Genesis VA1.8 Audio Mod - Need Help!

[FarmMachinist]

Need help ... finished audio mod and all I'm getting is a slight audio pop when I turn on the system ... and nothing else!

I followed the tutorial over at Console Mods to the letter so I'm not sure what could be the problem.  Checked my circuit and my solder points are good so either the schematic, guide, etc was wrong because I've double checked my work and it's spot on!

Any ideas???


... my first time etching a pcb (used Eagle CAD) ... the process was fun ... but it would be even better if I had sound

Nevermind ... I've messed around with it till I'm blue in the face ... apparently it doesn't work with my particular motherboard.  Oh well ... glad I wasted my time ... I'll be a little more selective about mods I try from now on
