Hello everyone, Post here if you need help with Patching AppleHDA or want to do it yourself but still needs help How to get Codec Dump : 1. Use Ubuntu or Any Version of Linux Distro (Note : Use the latest version of Linux and Alsa drivers ) 2. Open Terminal and copy paste below Code : cd ~/Desktop && mkdir CodecDump && for c in /proc/asound/card*/codec#*; do f="${c/\/*card/card}"; cat "$c" > CodecDump/${f//\//-}.txt; done && zip -r CodecDump.zip CodecDump 3. On Desktop there’s a folder/file name Codec_dump 4. Save this to safe place Troubleshooting : No sound/audio after installation : you must use IRQ Patch in DSDT or Clover Config.plist DSDT : use system IRQ patch from laptop patches Clover Config : Fix HPET, Fix RTC, Fix TMR in ACPI => DSDT => Fixes Generate Troubleshooting files : DSDT or SSDT Patched if you using one Clover config.plist IOregistery saved file using IOregisteryExplorer v2.1 Mac OS version you are on Screenshot of System Information/Hardware/Audio/Intel High Definition Audio Clover files i Clover config.plist ii Clover bootlog -> Type in Terminal below commands : save ouput bdmesg Type in Terminal below commands : save ouput kextstat | grep -y AppleHDA IOregisteryExplorer v2.1 : IORegistryExplorer v2.1.zip

Hi I hope someone can help or point me in the right direction. Dell E7240 currently running HS but have run Mojave also. I can’t get the audio to work with the ALC292 and patched AppleHDA kexts always shows no output device. Found a guide which said to apply hot patches using clover configurator which I have done, each time I rebuild the Kext cache and can see the Kext being loaded, but still no audio, injected layout 12 which apparently it’s the supported for the codec. The voodooHDA Kext works but it screws up the mic a lot. hope someone has an idea what to try next I would up load files but for some reason I cant log in on a laptop as the account shows locked out, but I can only my phone.

Since I added my patch to AppleALC (version 1.2.1 or newer) so we can use it in this Dell type. You can download attached file or latest version from here: https://github.com/vit9696/AppleALC/releases AppleALC1.2.6_Lilu.1.23.zip

Hi everyone. I have the k53sv laptop with i7. After EDP has been successfully installed, everything seems to work fine except the audio. It doesn't work at all with AppleHDA patch (there is no output and input devices found). The VoodooHDA makes speakers work but the mic, neither internal nor external (audio in), doesn't work. Any ideas how to fix this?

Hi everyone, I got my E6400 working beautifully using Lion and the EDP process, however whenever I listen to audio in iTunes, or in any other app, if the volume maxes out there is a really loud crackle, or clicks and general distortion. I am using VoodooHDA 2.7.3 which was installed by the EDP. I've also removed AppleHDA manually because having them both was causing KPs. It worked fine in Snow Leopard, so I would like to know if anyone knows what is causing the issue?
