Problem sound and display glitch with MacOS Mojave 10.14

[MustafaMESSI]

Hello guys

first excuse my language if I make mistakes

I recently installed macOS Mojave 10.14.2, but I faced some problems :

1- The sound doesn't work sometimes when I boot sometimes work and other times doesn't work.

2- When I open App Store or other apps and go to some pages that contain videos or gif, the display start to freeze for a while randomly until I close the app.

3- when sound is work, Siri doesn't work correctly, I guess it's read some noise for mic. but works fine with Bluetooth headsets.

4- the Ethernet doesn't work.

5- Boot Glitch for about 2 second, it's not that important to me but if there is fix this will be better.

everything else work fine.

I tried to install may kexts for VoodoHDA but not work.


I installed high Sierra before and doesn't have these problems.

my Laptop is :

Dell Inspiron 5559
Intel Core i7 6500U
Intel HD Graphics 520
AMD Radeon R5 M335
