Fix microphone on my Dell Latitude E7450

Hi guys, yesterday I install Olarila Clover Mojave 10.14.6 on my Dell Latitude E7450

For specs:

Core i5 5300

4GB ram

SSD 256GB

Intel AC 7265

​

Everything I fixed successfully but the integrated microphone is not working although it show in the system preferences. So how can I fixed, do I need to add kexts or edit config.plist? Plz
