You could use a ticker for toggle: #include <Arduino.h>
#include "SD_MMC.h"
#include "Audio.h"
#include "Ticker.h"
#define I2S_LRC 26
#define I2S_DOUT 25
#define I2S_BCLK 27
#define I2S_MCLK 0
#define SD_MMC_D0 2
#define SD_MMC_CLK 14
#define SD_MMC_CMD 15
String ssid = "*****";
String password = "*****";
Audio audio;
Ticker ticker;
int8_t toggle = 0;
bool start = false;
void t10s(){
toggle++;
start = true;
if(toggle == 3) toggle = 0;
}
void setup(void) {
Serial.begin(115200);
WiFi.begin(ssid.c_str(), password.c_str());
while (WiFi.status() != WL_CONNECTED){
delay(1500);
}
pinMode(SD_MMC_D0, INPUT_PULLUP);
if(!SD_MMC.begin("/sdmmc", true)){
Serial.println("Card Mount Failed");
return;
}
audio.setPinout(I2S_BCLK, I2S_LRC, I2S_DOUT, -1);
audio.setVolume(21); // 0...21
ticker.attach(10, t10s); // every 10 seconds
audio.connecttohost("http://mp3.ffh.de/radioffh/hqlivestream.mp3");
}
void loop(){
audio.loop();
vTaskDelay(1);
if(start == true){
start = false;
if(toggle == 1) audio.connecttoFS(SD_MMC, "A17A1203615.mp3");
if(toggle == 2) audio.connecttohost("http://mp3.ffh.de/radioffh/hqlivestream.mp3");
}
}
void audio_info(const char *info){
Serial.print("info: "); Serial.println(info);

Thanks for the reply. My latest code: `` #define I2S_DOUT 22 /* #define SD_CS 5 Audio audio; String ssid = "xxxx"; int8_t toggle=0; unsigned long changeChannels=millis(); void setup() void loop() void audio_info(const char *info) { |

What does the serial monitor say? According to your description, it is possible that the SD card or the file was not found. SD_MMC is a bit more reliable, but in general it doesn't matter where the file is stored. |

Hello
I am using the ESP32-audioI2S-master library, SPI library for an SD card reader, a pcm5102
i2s DAC, and a headphone.
I want to switch (on-the-fly) from internet radio to SD card, and back to internet radio.
I can sequentially switch from internet server1, to server2, then to the SD card with no
problem. But when I try to switch back to server1, there is no more audio unless I reboot.
Below is my code. Does anyone have an idea on what is happening? Thank you!
