"Simple Audio Player for Arduino Zero" - SD card will not initialize

Dear community

Despite many & repeated attempts, the sketch "Simple Audio Player Zero.ino" does not work.

Problem:

  • The micro SD card will not initialize.The serial monitor reports after uploading the sketch: "failed!"

Hard & Software:

Soundfile:

  • Name: test.wav
  • 88200 Hz, 8-bit unsigned PCM mono

Now I can not go on - what am I doing wrong?

I would be grateful if someone could help me
