[Maitresinh]

ok done

here is my config file after edit

-------------
disable_splash=1
disable_overscan=1
hdmi_drive=2
hdmi_blanking=1
#dtparam=i2c_arm=on
dtparam=i2s=on
dtparam=audio=on
dtoverlay=audioinjector-wm8731-audio
#dtoverlay=pi3-disable-wifi

---------------------------------

Rebooted. Moode is running, but there is no new i2s device, at least no "audio injector" one in the list
