Try replacing the pinMode 2 through 13 with the below
pinMode(6, OUTPUT); //MP3_XCS
pinMode(7, OUTPUT); //MP3_XDCS
pinMode(8, OUTPUT); //MP3_RESET
digitalWrite(6, HIGH); //negate XCS
digitalWrite(7, HIGH); //negate DXCS
digitalWrite(8, LOW); //Put VS1053 into hardware reset
Put the above code “as the first thing”, into the setup() of each INO that you try: SdInfo.ino, SdFormatter.ino and MP3Shield_Library_Demo.ino.
