Is this the proper way to use the code from the library to test the playback of audio track 0000.ad4...
void loop() {
//Plays synchronously an audio file. Busy pin is used for this method.
wtv020sd16p.playVoice(0);
}
}
It seems I have everything correct but my speaker is only outputting a strange sine wave type beep with a half second gap between playing, and the sound is very, very low. Without having to order a bunch of SD cards to test, does anyone know what's going on here?
