Hi, I’m nearly done with my control surface A midibox sid, but I’ve hit a road block. There is no sound output from the SID module.
The core seems to be functioning fine, LCD is working, interconnect test passed, I have 12V at SID pin 28 and all the other pins look OK. I loaded the sid test tone application, loaded fine. However, I get no sound at all from the audio out.
Wiring looks ok, I think. I have the 0 pin on J3 going to tip and the ground going to the sleeve. I am using 3-conductor jacks, and I left the ring conductor open since it will be shorted to sleeve with a TS connector, right? Suppose I had erroneously switched the two pins, would I get any sound that way?
Could this be some wiring problem to my audio jack? If the interconnect test passed, can I fully rule out the possibility of a flaw on the module? Could it be a dead SID chip? Any tips at all?
Thanks ---- G
