How to read I2S audio input

[joanlo]

Hi
I plan to connect an ADC to RPI through the I2S port. I need to read the audio input from I2S to do a audio capture.
I have the Raspberry PI 2 B with Raspbian Jessie.

What steps I have to do to read the digital audio from the I2S port.

Thanks in advance.

You have to compile a kernel module - I wonder why this is not in included
in the raspberry pi linux or is it now ?

Hi Carla
I have followed your indications and works fine.
Linux arecord command works ok but in Qt, audioinput not detects the audio card.
Thanks
