I use ESP32-WROOVER-DEV board and I want to implement both I2S audio and Camera function. But audio does not play at all when I start esp_camera_fb_get().
I use the library for audio as bellow, and I2S amp MAX98357A is attached to the board.

I confirmed that the single function for camera and audio separately, and they works fine as independent. But not in simultaneously.
I'd like to know that this is even possible.
