Asus Z97E seems to be compatible.

I'm a bit puzzled that my Motherboard Asus Z97E was not listed among the compatible motherboards. Upgraded from EC to High Sierra without a hitch, tho I didn't expect it to work as it was no longer listed as compatible. I did have to use an external USB sound dongle but that was the case even when it was listed as compatible.

Any ideas why? Just curious or where to list it as compatible with a note on the sound?
