I have an issue with my NUC6CAYH (Apollo Lake). LE 8.0.2, latest BIOS and LSPCon 1.6.6 firmware. Audio is being decoded (HDMI) to my LG TV (no bitstream).
Under Audio Settings I see the device setup as LG TV on DisplayPort 0. All is good.
If I turn off the TV and turn it back on it now shows LG TV on HDMI 0. At this point my audio no longer works, need to reboot.
On the Kodi forum it was recommended to set my EDID. I tried this both the manual way and getedid script. Both seem to work "a bit", meaning a give the TV a toggle or two and see it stays as DisplayPort. But after several hours it will still revert back to HDMI, requiring a reboot.
Not sure this is a Kodi, LE or Linux bug at this point. I know the Apollo has a number of HDMI/audio issues but I thought they were all around bitstreaming.
The Kodi log doesn't show much, no errors. Devices are discovered the same:

EDID seems to load ok (from startup log):

After several hours when I turn the TV on and check settings it's still DisplayPort but as soon as I try to play TV (no audio) I get:
