Please check whether your HDMI firmware is up-to-date, too. Audio is related to HDMI.

yes i did this now upgraded from 1.73 to 1.77

now i see the hdmi output 4 time choose the first and still no luck

UPDATE SOLVED (my case)
FIXED IT and thats who i did it (all the things i did)

updated the bios -- didnt help
updated the HDMI FW -- didnt help still nothing
disabled the Audio DSP -- didnt help
downgraded to libreelec 10
ran echo "blacklist snd_soc_skl" > /storage/.config/modprobe.d/blacklist-snd-soc-skl.conf
enabled passthrough hdmi 1
and it started to work not sure why

any way checked the setting in libreelec 12 it didnt work

then I tried libreelec 11 the last nightly version
ran

 echo "blacklist snd_soc_skl" > /storage/.config/modprobe.d/blacklist-snd-soc-skl.conf

enabled passthrough DISPLAYPORT and output on displayport (NUC8i3) doesnt have a displayport.

buy it worked anyway from hdmi

didn't tried it again in libreelec 12 (using the DP as output with passthrough on DP)

thanks for all your help
