ESP32-2432s024c Use SD Card, Internal DAC output and I2S MIC

[elik745i]

Guys great appreciation for helping me out with my little project. I have successfully implemented Battery readout directly from the GPIO to interface. Now I need some kinda idea on how to output sounds through internal DAC (I understand that that might be noisy) and MIC input using I2S.
My custom build for ESP32-2432s024c is here for those who might be interested: https://github.com/elik745i/ESP32-2432s024c
Fully functional and working great.
Thanks
