This is not true.
The M5Stack ESP32 Camera Module is using a OV2640 with a "hack" of the I2S interface because this ESP32 subsystem is able to DMA for the data. The camera control is over the Serial Camera Control Bus (SCCB) protocol that is using I2C routines. Additionally the GROVE connector makes the I2C accessible for peripherals.
The M5Stack ESP32 WROVER with PSRAM Camera Module additionally has the BME280 and MPU6050 on a second I2C.

But who knows? Still there are no up to date schematics. I mean something with the actual wiring of the PCB. Not the overview picture. Which is btw only posted on Aliexpress:

My opinion: It is a silly idea to share the camera VSYNC and SIOC with the BME280 and MPU6050.

@Calin Hold your ear on the "mute" speaker. There is still noise with your code.

THX for the hardware mod suggestion.

I want to add

• Upload a complete M5Stack Fire schematic of the current revision. There is none in the docs.
