Fourdee over at Dietpi->https://github.com/Fourdee/DietPi made a script for an automated DietPi + MoodeAudioV4B9 install..
works here (RPI3B + I2S-ES9028Q2M) fabulous and with absolut no issues (install/compile about 35-45min)..
„Skript“/infos are here->https://github.com/Fourdee/DietPi/issues/1223
„Currently in testing, under RPi Stretch.
Steps to test the DietPi + moOde installation:
Download the DietPi Stretch image and write to SD card: http://dietpi.com/downloads/testing/DietPi_RPi-armv6-(Stretch).7z
Download the following automated installation file http://dietpi.com/downloads/conf/moode/dietpi.txt and save it to the SD card /boot/dietpi.txt. This will automatically install moOde on 1st run.
Connect HDMI if you want to see the installation process.
Eject SD card, pop into RPi and power on“
(PS.: its then „dietpi/“ in the browser-line and not „moode/“ and the ssh-login data is: user=root and pass= dietpi)
