Segmentation fault when ofxMaxim playes sample on Raspberry pi

Hello,

I am using ofxMaxim to play a sample. The code works on Windows but on Raspberry pi 3 I get a Segmentation fault. If I use a sine oscillator to make a tone it works on both machines.

Here is the code, is very basic and it is based on the sample player example of ofxMaxim:

#include "ofApp.h"

//--------------------------------------------------------------
void ofApp::setup() {
	sampleRate = 44100;
	bufferSize = 1024;

	soundStream.listDevices();
#ifdef TARGET_RASPBERRY_PI 
	soundStream.setDeviceID(2);
#else
	soundStream.setDeviceID(1);
#endif

	soundStream.setup(this, 2, 0, sampleRate, bufferSize, 4);
	tsiks.load(ofToDataPath("tsiks.wav"));
}
//
void ofApp::audioOut(float * output, int bufferSize, int nChannels) {
	for (int n = 0; n < bufferSize; n++) {
		output[n*nChannels] = tsiks.play(1);
		output[n*nChannels + 1] = tsiks.play(1);
	}
}
//--------------------------------------------------------------
void ofApp::update() {
}
//
void ofApp::draw() {
}

and here is the error:

Any ideas?
