Then you need to get in touch with the developers and have it added, I have not tried it with LibreElec
I'm using it successfully with a Volumio (volumio.org) installation, not LibreElec.
Just happened to stumble over this thread searching for audio jack clues on an AZW Z83II.
Seeing this thread is called "AZW Z83 II Support", I would like to add another issue.
I have been trying to get sound from the audio jack, did anyone get this working?
next to the broadcom firmware for the OP's wifi chip on the Z83 II (brcmfmac43455-sdio.bin), you also need to supply the nvram text file.
A 'dmesg' would probably show that it cannot find it:
===> brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac43455-sdio.txt failed with error -2
Copy the attached .txt file to the same folder (/lib/firmware/brcm).
