[SOLVED] Dell E7440 display and sound problem

Recommended Posts

Hi everybody,

 

After updating, a kexts fell a bit ... :(

At the moment I noticed that picture quality is terrible and does not recognize a sound card.

 

On the attached pictures, you can see a kext and what kind of image you are currently looking for.

 

What you need to know: I use a Dell E7440, A21 BIOS, E7440_A21 kext package with a 4411 clover.

 

Can anyone help me with what I can do?

Replace kext with this one  AppleHDA_ALC292.kext.zip

Repair permission and rebuild cache

 

Graphics issue could be due to you having duplicate kext in /E/C/k/Other and /L/E

If they're not in the LE folder, you should keep them in /E/C/kexts/Other

I have not found any duplication at this time, and I have tried to reinstall the file as "AppleHDA_ALC292.kext" attached to it as an attachment, but nothing ...

You have these in /E/C/kexts/Other and in /Library/Extensions. I call that duplicates
