Good Morning.
I am a university student, and in business practices I am working with the Teensy 3.5 board and the Audio Shield, all in the Arduino IDE 1.8.7 environment.
The problem is the following:
I used to load this program (It's the example 1_02 of Audio> Tutorial) on my board and I heard a beep, as it should be.
However, one day I charge that program again and nothing is heard; instead, the serial monitor displays this message.
The Teensy board and the Audio Shield are connected in this way:
As I said, you do not hear that beep that should be heard. I know the problem is not the Teensy board, because it responds well to other programs, such as the Blink. Therefore, I suspect that the problem is in the Audio Sield.
My question is: is there any way to check my Audio Shield plate? It is to know if something is broken or if a short circuit has occurred. If you could indicate or proportional any program or example that indicates to me if the Audio Shield is broken, I would appreciate it very much.

// Part 1-2: Test Hardware
//
// Simple beeping is pre-loaded on the Teensy, so
// it will create sound and print info to the serial
// monitor when plugged into a PC.
//
// This program is supposed to be pre-loaded before
// the workshop, so Teensy+Audio will beep when
// plugged in.
