I fixed it. The culprit is AudioDxe.efi Driver. Remove it since Windows sound > startup sound.I install MacOS after installing Windows on same hard drive. To dual boot, I use this trick (Rename bootmgfw.efi to bootmgfw-orig.efi) to launch Clover instead of Lenovo/Windows bootloader. When I launch Windows this way, the audio is not working. However, if I undo the trick I used and let it launch Windows directly without Clover, the audio is working again. How can I fix this?
The reason the audio is not working is because of Intel Smart Sound Technology(Intel(R) SST) OED driver malfunctions. It has a code 10 error(FW did not sent FW Ready notification). This problem does not exist if I launch Windows without Clover.
This is the boot menu. Using BOOTICEX64, I found out that Windows Boot Manager and option 2 point to the same file. Windows Boot Manager is suppose to be the default Lenovo/Windows Bootloader.
