Omerlatif5490 0 Posted January 12 Author Share Posted January 12 No. I just hear a continuous beep from the headphones, speakers work fine though. I tried installing HoRNDIS because my WiFi card is not supported, I added it to the kexts folder, used ProperTree to get a snapshot for the config.plist, but upon reboot it gives me a kernel panic error.

Moderators Jake Lo 1702 Posted January 12 Moderators Share Posted January 12 I don't use propertree, so I don't know if it'll automatically add every kexts/plugins and SSDT* found in the OC folder You can manually copy the Horndis kexts from your Config to the working Config file For HP, try adding CodecCommander.kext and this SSDT* I had changed layoutid to 11, you had 14 before. Try other layoutid = 13, 16, and 56 SSDT-ALC256.aml.zip 1 Quote Link to post Share on other sites
Omerlatif5490 0 Posted January 13 Author Share Posted January 13 layoutid 21 finally works, thank you so much. How do I manually add kexts to config.plist? Whenever I add a left I always update the config file from ProperTree and it always works, no idea why it broke this time Quote Link to post Share on other sites
wribeiro 0 Posted Thursday at 04:31 PM Share Posted Thursday at 04:31 PM @Omerlatif5490 I have the same model Latitude 5490, I have installed Big Sur using the efi provided by @Jake Lo here, and with minor adjustments I was able to install BigSur. Now I'm having problem with distorted sound using headphone. Have you configured any of those files mentioned above (CodecCommander or SSDT-ALC256.aml.zip)? Can you tell how you manage to fix it? Thanks Quote Link to post Share on other sites
Moderators Jake Lo 1702 Posted Thursday at 04:39 PM Moderators Share Posted Thursday at 04:39 PM @wribeiro change layout-id to 21 as stated by Omerlatif5490 just add to bootarg under NVRam in the Config file alcid=21 Quote Link to post Share on other sites
wribeiro 0 Posted Thursday at 04:51 PM Share Posted Thursday at 04:51 PM I have tried all ids under the ACL256, none of them worked. Maybe its something in my EFI folder. I'll upload it here, I appreciate if you can help me. ps.: I have excluded the intelbluetooth kext to not exceed the file size limit OC_5490.zip Just posting again do say that is working now. I compared my EFI folder with Omerlatif5490. In my drivers folder was missing the AudioDxe.efi. I have copied it and now the sound is working perfectly through headphone jack.
