Here is an other small Sound Player you can use with Arduino: SOMO-II. I’ve used the board with an Arduino Pro Micro 5V. As an alternative you can use the inexpensive DFRobot DFPlayer Mini (~7€): Here
Also I’ve written a small example sketch you can use. The communication goes through the Serial1 port of the Arduino ProMicro and all the commands will be set stable. This is a big advantage in contrast of the WTV020 Sound Player.
Hint: If you here destroyed sound, then you can try to unplug the USB Connector and apply 3.3V to the VCC and GND pins of the Arduino ProMicro.
