Will test all this night, but I am pretty sure this module will only play certain ad4 and Wav files encoded in the right rate. As read in other websites, this one and somo-14d shares the same IC so connection diagram should be fine, even the sketch program should be correct. Your problem was the Vcc and mine the connection. Keep you posted. We are in the same boat. And If anybody have this working, we will really appreciate any help.
i used the somo tool to create the ad4 file
