Tsunami wav trigger (Qwicc) sound problem - After re-run the sound is much louder

Sensors Sound & Audio
1

We have the following problem. The tsunami is part of an installation. It plays a sound layer for 3 minutes that it loads from an sd card. It stops and then waits for it to be started again.

When it starts again, however, the sound is much louder. It looks like as if the sound layer is still in its memory and also reloaded from the sd card. Like the tsunami is playing 2 identical sound layers at the same time.

What helps is pressing the reset button, but the tsunami is built into the installation. We can’t reach the reset button when the installation is running.

Any idea what the problem is or how to solve this issue? The tsunami is controlled by a redboard, via Qwicc.

You might get more help if you post your Redboard Arduino code.

Thanks for responding! Hereby the redboard code. The redboard recieves data from an Arduino Uno for tiggering the audio layers. The Arduino Uno is connected to GSR sensors.
