...for a freelancer who can modify my code for a ESP32 using the ESP8266Audio Library and get it to play the video which is sync'd with the audio. The audio file is read from an SD card using the SD_MMC.h library. I'm using the ESP8266Audio Library to play the file. The output should go to a Max98357A amplifier that uses DOUT on pin GPIO_22, BCLK on pin GPIO_26, LRC on pin GPIO_25. The video portion works fine. The problem is, we can't hear anything from the speaker. But we know the amplifier and pinouts are correct because they function using another library. The timeline for these modifications is short-term, within a week. We need someone to help us get this working. Ideal Skills and Experience: - Proficient in programming with the ESP32 for video us...
