Hey All,
I've run into something for the first time. I've been building an audio project for several years now using Teensy+Audio, and today after assembling and testing one I cannot get sound to come out of the line-out port. The headphone port works fine. It's a simple project that has a mic input, line-out, and plays WAV files from the SD card. Same sketch I've been using. I assembled one before this one and it works fine. I've tried replacing the jack (3.5mm stereo), audio cable, wires from jack to Audio shield line-out poles, using the second set of line-out poles, running several different WAV player example from the Teensy, library, triple checked all the solder points and made sure no pins are cross connected. I've checked continuity from the end of the stereo audio cable all the way to the pins on the Audio shield, including ground, and it's got continuity. I'm not sure what else to try. Has anyone seen this before and is it possible I just got a bad board?
