Hi there,
sorry for posting in the wrong thread, but your Audio Issue Thread is closed. I had the same Problem on a PAL SNES. Bridging the I and the O on the Place where the 7805 is originally connected ( I think you removed it when you feeding 5 Volts from the screen ) gave me Audio. If it works ...

Basicaly, I'm making a SNES portable for my best friend - it's a late birthday present, and i want it done before I go back to uni. I'm in the UK, so ...
