I’ve pretty much come to he conclusion that one of the Sid modules is dead. I haven’t been able to tack it down to a specific part unfortunately. I get extremely low volume from one of teh modules no matter which sid is in it. I swapped out the voltage regulator thinking that may have been it, but no love Eventually ‘m gonna have to order a new one. The project is gonna have to be put asside for a while though as I was just given three weeks notice at work, which I knew was coming. They’ve shipped my job to India. 🙁
