Error loading wav file dinamically (audioSample defined by a static array or malloc)

[brunocantisano]

I wrote an audio.wav file in my data folder. Every time I try to load this file dinamically, my ESP restarts:

My array is static:

include "XT_DAC_Audio.h"

define RelayAudio 25

XT_DAC_Audio_Class DacAudio(RelayAudio,0);

void play() {
File root = SPIFFS.open("/audio.wav"); if (root) { size_t sz = root.size(); unsigned char audioSample[sz]; if (root.available()) { root.read(audioSample, sz); } root.close(); XT_Wav_Class Sound(audioSample); DacAudio.FillBuffer(); if(Sound.Playing==false){ // volume vai até 100 //DacAudio.DacVolume=100;
DacAudio.Play(&Sound); }
} else { Serial.printf("Error to open audio.wav!"); } }

OR (with malloc)

include "XT_DAC_Audio.h"

define RelayAudio 25

unsigned char * audioSample; XT_DAC_Audio_Class DacAudio(RelayAudio,0);

void play() {
File root = SPIFFS.open("/audio.wav"); if (root) { size_t sz = root.size(); audioSample = (unsigned char *)malloc(sz); if (root.available()) { root.read(audioSample, sz); } root.close(); XT_Wav_Class Sound(audioSample);
DacAudio.FillBuffer(); if(Sound.Playing==false){ // volume vai até 100 //DacAudio.DacVolume=100;
DacAudio.Play(&Sound); }
} else { Serial.printf("Error to open audio.wav!"); } }
