In the end I will need the program to
The key phrase there is "in the end". You don't need that right now. Right now, you need the thing to make some noise. Right?
void loop()
{ // Down here, where it belongs
playfile("Pink_Try.WAV");
}
If this doesn't make any noise, the file doesn't exist on the SD card or the hardware is miswired. No amount of f***ing around with code will fix either of those problems.
