Hello all
For your question about the gpu and i2s and sound i tested my script and it seems to work fine on my OPI zero 2w
With your fresh install of the last Dietpi 9.15.2 version
the script

mkdir -p /boot/overlay-user
cd /boot/overlay-user

# Install the device tree compiler

In a terminal just a few command when you are connected
sudo nano sound.sh
Copy and past the script
Ctrl+o to write the line and Ctrl+x to save and exit
Run the script
sh sound.sh
Inject the user-overlay
G_CONFIG_INJECT 'user_overlays=' 'user_overlays=sound-hdmi-jack-i2s0-hat' /boot/dietpiEnv.txt
And reboot
That’s all
