That's why I went with a Soundblaster Play 3 USB sound device. It's recognized OOB and solved the constant problem of fiddling with onboard sound after almost every update.Easy update from macOS 13.3.1(a) with opencore 0.9.2 but onboard audio has disappeared. Motherboard GA-X99-UD3P with xenon ES-2699. Onboard audio works fine on Fedora linux.
