audio error in Running Chatgpt on ESP32 with audio output

[Agitha]

i have done this Running chatgpt on esp32 with audio output , the project worked well, I have attached outputs as well, but now when I asked question the answer only appears in serial monitor the audio output is not appearing , in earlier output there was lot of data about audio appeared but now simply question and answer is appearing,I have attached that output screenshot as well , how to rectify this

Code: Select all

#include <Arduino.h>
