Comment on the used kernel version:
Users of the newest version of Raspbian Jessie (kernel version 4.9.35-v7+) have to update their kernel first, because needed modules weren't included at this time.
The current kernel version can be checked with the following command:
> uname -a
Update to Kernelversion 4.9.80-v7+ (higher versions also possible) with:
> sudo rpi-update 5c80565
Installation guide for Raspbian (in a Terminal-Window or SSH-Client):
(Volumio users see below)
Install git:
> sudo apt-get install git
Clone files:
> git clone https://github.com/MKSounds/ADAU1701-I2S-Audio-Driver-for-Raspberry-Pi.git
Copy overlay file to overlays directory:
> sudo cp ADAU1701-I2S-Audio-Driver-for-Raspberry-Pi/adau1701-i2s.dtbo /boot/overlays
Relink the overlay to the device tree: Therefore config.txt has to be modified.

If you want to play files which don't use 48 kHz sample rate, you have to resample the audio data. Therefore a ALSA config file will be used, which will affect the whole audio output of the system.

> sudo nano ~/.asoundrc
Copy and paste the following lines (paste by right clicking):
