As expected, no sound at all at pin 3 of the scart socket. At R647, I got noise on the side closest to the CXA chip, the same applied to Pin 49. From pin 1, I got proper audio.This confuses me as it sounds like the chip is at fault again as there is audio in at pin 1 from the encoder and no corresponding audio out to pin 49.It will be interesting to hear your comments on this one.By the way, I made my probe using the 1.25mm, centre copper core from CT125 cable which I sharpened the one end to a point, used heatshrink for the whole length except for about 3mm of tip, using small twin core cable with small insulated crocodile clip on other leg and the 3.5mm socket on the other end, heatshrinking all exposed metal.</blockquote>
