The ESP is really 26MHz, so it is impossible to get this clock divided to 12MHz.

The 26MHz is the crystal frequency. Internally a pll generates a 160MHz clock which feeds the logic including the i2s circuitry.
This still doesn't allow you to get 12MHz accurately but I think one could get 12.3

The 26MHz oscillator could be changed.
Currently, the frequency of crystal oscillators supported include 40MHz, 26MHz and 24MHz. The accuracy of crystal oscillators applied should be ±10PPM

Hi,
But how to get 12.3 using Arduino?....
