Problem Playing More Than 1 mp3 When Called by Name

[chuck808]

Hello,

I thought I was trying to do something fairly simple, but either I'm going about it wrong or more likely I'm an idiot.

I want to use a button to trigger a sequence that first plays an .mp3 from and SD card, pauses for a set amount of time then plays a second .mp3 file, then moves on with the program. Simple right?

Firstly, I simply took the audio.connecttoFS(SD, "/test1.mp3"); from setup() and placed it in the loop(), then added delay(2000); audio.connecttoFS(SD, "/test2.mp3"); But nothing played, not even if I just put the first part in the loop().

Next, I tried using an array to store the mp3's in

const char* audiofilenames[] = { "test1.mp3", "test2.mp3" };

Then tried to accessed them using the following (this work fine for 1 mp3),

void loop() {

  audio.loop();

  buttonState = digitalRead(Button1);

  if (buttonState != lastButtonState) {
    if (buttonState == LOW) {
      Serial.println ("GATE SEQUENCE BEGIN");

      audio.setVolume(15); // 0...21
      audio.connecttoFS(SD, audiofilenames[0]); // Play Audio 1
    }
  }
  lastButtonState = buttonState;

}

However, when I add a second file

void loop() {

  audio.loop();

  buttonState = digitalRead(Button1);

  if (buttonState != lastButtonState) {
    if (buttonState == LOW) {
      Serial.println ("GATE SEQUENCE BEGIN");

      audio.setVolume(15); // 0...21
      audio.connecttoFS(SD, audiofilenames[0]); // Play Audio 1
   
      delay(1000);// do something else

      audio.connecttoFS(SD, audiofilenames[1]); // Play Audio 1
    }
  }
  lastButtonState = buttonState;

}

This just skips over the first file, runs the delay then plays the second file once, meaning I have to reboot to run it again. I have also tried using void audio_eof_mp3(const char *info), but with no luck

Can anyone spot the mistake I'm making.

Thanks

I have a similar issue. After I switched the log level to verbose, I saw that the mp3 decoder wasn't able to allocate enough memory to play the mp3 and simply stopped doing it. Maybe changing the log level will also provide some clue for you.

Is this solve? I have the same problem...

Sorry for the delay, I hadn't seen this.

No, I didn't resolve this issue so I went another way.

Noob question, how do I access one sound specifically? I just tried setting up audio. , audio1. and so on but that is just ending up in playing the two audios at the same time. Let's say I have two functions and each function should play a specific sound?
So like
audio.loop(0); playing If_I_Had_a_Chicken.wav
and
audio.loop(1); playing mechanik.mp3

That does not work. There is no mixer to combine pcm streams from two audio objects. Please have a look here: https://github.com/earlephilhower/ESP8266Audio

Nah I don't want to mix it, I just want to play one wav at a time... just to pick from a set. Think of a soundboard like thing.
