I am trying to run the SD Card Test sketch.

I have loaded 3 of the audio files onto a 4gb Micro SD card.

When I run the sketch, I hear no audio.

Do the files need to be in any particular order?

Do I need to prepare the card in any way?

How would I debug this?
 
The SD card test, File > Examples > Audio > SdCardTest, does not play any sound. It reads 4 files and prints info to the Arduino Serial Monitor.

You're supposed to put these 4 files onto the card (as explained in the comments of that test sketch).

After uploading, select the serial port in Tools > Port. Then open the serial monitor to see the info.


Maybe you meant a different "SD Card Test sketch"?
 
Use File > Examples > Audio > WavFilePlayer.

Like the card test, put those 4 files onto the card. Or edit the code for the actual file names you have on the card.

Run the card test, or File > Examples > SD > listfiles if you need to check which files are really on your card and what their 8.3 names really are.
