Strix Z390-i no back audio after bios upgrade

Hardware: CPU: i7 9700k
GPU: Sapphire Pulse RX 5700 XT
RAM: Ballistix Sport LT 32GB Kit (16GBx2) DDR4 2400 MT/s (PC4-19200)
Motherboard/Laptop model: ASUS ROG Strix Z390-I Gaming
Screen(s) Number:1
Screen(s) Resolution: 4K
Audio Codec: S1220A
Ethernet Card: Intel® I219V
Wifi/BT Card: BCM94360NG (I replaced the one that came with the MB)

After upgrade, I had to re-do the bios settings changes and everything worked. Except for audio. I had a 3 month old AppleALC and only front jack was being detected. I upgraded to latest AppleALC and then not even front input is detected. I saw no audio device and AppleALC kext is not even loaded.
