Missing Data in the I2S Line for a ESP32-S2 Solo Module

[ClaudioFoscan]

Hi

i'm Using your Library with a ESP32 Wroom 32 Board and an MAX98357. Works as expected.

I like to use the same Setup with a ESP32-S2 Solo Board (cause of the internal USB-HW). the exactly same Code is used and produces some Dropouts in the I2S Data ... not the CLK-Line or the LRC-Line, they stay constant switching but on the Data-Line i see some missing Data between and the sound is broken. if i use an mp3 instead of the Webradio the speed is wrong with higher Bitrates and the Data is also dropping ...

is it possible that the ESP32-S2 has lower performance or are there some bugs for this SoC?

Anyone else the same expereance?

The used example Code : `

include "Arduino.h"

include "WiFi.h"

include "Audio.h"

//Digital I/O used  //Makerfabs Audio V2.0

define I2S_DOUT 22

define I2S_BCLK 26

define I2S_LRC 25

Audio audio;

String ssid = ""; String password = "";

void setup() { // put your setup code here, to run once: Serial.begin(115200); Serial.println("Wroom Test with I2c");

Serial.print("I2C init ... "); audio.setPinout(I2S_BCLK, I2S_LRC, I2S_DOUT); audio.setVolume(5); // 0...21 Serial.println("done");

WiFi.disconnect(); WiFi.mode(WIFI_STA); WiFi.begin(ssid.c_str(), password.c_str()); while (WiFi.status() != WL_CONNECTED) delay(1500); Serial.println("wifi connectet...");

Serial.print("Connect to SRF3 ... "); audio.connecttohost("https://stream.srg-ssr.ch/drs3/mp3_128.m3u"); Serial.println("done"); }

void loop() { // put your main code here, to run repeatedly: audio.loop(); }

// optional void audio_info(const char info){ Serial.print("info "); Serial.println(info); } void audio_id3data(const char info){ //id3 metadata Serial.print("id3data ");Serial.println(info); } void audio_eof_mp3(const char info){ //end of file Serial.print("eof_mp3 ");Serial.println(info); } void audio_showstation(const char info){ Serial.print("station ");Serial.println(info); } void audio_showstreamtitle(const char info){ Serial.print("streamtitle ");Serial.println(info); } void audio_bitrate(const char info){ Serial.print("bitrate ");Serial.println(info); } void audio_commercial(const char info){ //duration in sec Serial.print("commercial ");Serial.println(info); } void audio_icyurl(const char info){ //homepage Serial.print("icyurl ");Serial.println(info); } void audio_lasthost(const char info){ //stream URL played Serial.print("lasthost ");Serial.println(info); } void audio_eof_speech(const char info){ Serial.print("eof_speech ");Serial.println(info); } `

Dual core MC is required, please use an ESP32 or ESP32-S3
