Rock64 No Audio - Solved

[quote pid='35943' dateline='1520011480']

 setting Audio/audio device to I2S Analog stereo
The output is strong enough to drive a true Sennheiser headset (4 - 400 ohms)
Hope that helps...

So I assume a standard 3 pole headphone jack of 3.5mm works? And further guessing if a mic is used a 4 pole 3.5 jack is needed?
I will soon take delivery of my first Pine 64 product - RockPro64. I am wanting to get that audio-out jack working in LibreElec, if not already working.

On the latest Arch Linux, I had to install dtc to manage the device tree, then

# fdtput -t s /boot/dtbs/rockchip/rk3328-rock64.dtb /analog-sound status okay
# reboot

makes the built-in audio available. There are no controls, though.

Am struggling to get sound out of the cinch outputs on the DAC addon board.

Could one of you post a config, that is supposed to give me sound out of the cinch outputs?

I am currently using this image:
