I am having issues with this guide 7.5 MP3 Player with SD Card Support — SunFounder ESP32 Starter Kit documentation
I have an error where this import is not recognized, and am unable to get the speaker + mp3 working. I have the latest version of the ESP8266Audio library installed.
#include "AudioFileSourceSD_MMC.h"
fatal error: AudioFileSourceSD_MMC.h: No such file or directory
#include "AudioFileSourceSD_MMC.h"
It is possible that the files in your ESP8266Audio.zip library were not uploaded completely.
You are missing AudioFileSourceSD_MMC.h, which causes the error to be reported.
We suggest you delete the previously downloaded code and re-download the new code package package and unzip it.
Then reinstall the ESP8266Audio.zip library.
You use manual installation, installation tutorial steps to install:
https://docs.sunfounder.com/projects/esp32-starter-kit/en/latest/arduino/arduino_start/add_libraries_ar.html#install-lib-man
After successful installation, go ahead and run the sample code to see how it works.
Hi where are you getting the ESP8266Audio.zip library?
I have installed the library from this source GitHub - earlephilhower/ESP8266Audio: Arduino library to play MOD, WAV, FLAC, MIDI, RTTTL, MP3, and AAC files on I2S DACs or with a software emulated delta-sigma DAC on the ESP8266 and ESP32 but it is still not recognizing the following import.
#include "AudioFileSourceSD_MMC.h"
ESP8266Audio.zip is included in our product code package.
The path is:\esp32-starter-kit-main\c\libraries
You use manual installation, installation tutorial steps to install:
https://docs.sunfounder.com/projects/esp32-starter-kit/en/latest/arduino/arduino_start/add_libraries_ar.html
After successful installation, go ahead and run the sample code to see how it works.
Thank you for your help. Where can I find the URL to your product code package?

I also have an issue with this sketch:

what this dont work 
i am beginner 
my board is :SunFounder ESP32 Ultimate Starter Kit with Battery & ESP32-WROOM-32E Board, RoHS Compliant
and program : 7.5 MP3 Player with SD Card Support
please help me (excuse my english i am from quebec french)
Please describe the problem you are encountering in detail. Is there an error occurring during the code upload process? Are all the necessary dependency libraries correctly installed?
It would be even better if you could provide a video of the code uploading process, as it would help us analyze and resolve the issue more effectively.
