I updated my old laptop (LG P420) to windows 10 just because it suggested I do so. It ran win7 previously. After the update was finished it just kept booting. The windows logo appeared, then a black screen and what looked like a flicker of a window, then it started all over again.
There is a message 'for LG smart recovery, press F11' when you start the laptop. Pressing F11, however, resulted in a beeper sound, nothing more. All I could do was go into BIOS but that didn't help.
Since it seemed like a dead end and I wasn't able to do anything besides booting over and over I decided to install win8, which I had on DVD. I had to do a stand alone instal (without your existing settings) since I couldn't get into windows.
So that worked and I got into windows but there is no sound. It says no device has been installed for that. So I went to google for drivers but none of them work. There is a red X on top of my sound volume control icon.
The laptop in question: http://www.notebookcheck.net/Review-LG-P420-N-AE21G-Notebook.60803.0.html
Apparently it has:
Intel Cougar Point PCH - High Definition Audio Controller
Installing this http://support.lenovo.com/us/en/downloads/ds024884 just turns the screen black and nothing happens.
So if anyone has any idea how to either
1) get the sound working on win8.1
or alternatively
2) revert everything I did (I know it's possible to revert windows updates etc. but that is done in windows, and so it didn't work for me here), that would be great.
TL;DR: UPGRADING TO WINDOWS 10 JUST MIGHT FUCK YOU. Also it's pretty meh, I have it on my desktop.

This contains a list of the kext files I use for my hackintosh. You may eventually need to update your kext files when new versions of macOS comes out for continued support.
Kext Locations:
- If using the Clover method I like to stuff my kexts in/EFI/CLOVER/kexts/Other
- If not you can place non-required kexts in /System/Library/Extensions
Intel Cougar Point Chipset Driver for Microsoft Windows 7, Server 2003 R2, 2008, 2008 R2 and Small Business Server 2011, Multipoint Server 2011 - ThinkServer TS130. I have the same 'Audio device: Intel Corporation Broadwell-U Audio Controller (rev 09)' here (rev 08) though in a Dell laptop. Just spent some time to figure out the the correct kernel settings (on ver 5.1). Thanks goes to gentoo irc for showing in the right direction (iamben) and helping to solve the issue. 8086: 1E20 Name: 7 Series/C210 Series Chipset Family High Definition Audio Controller (Panther Point) 8086: 1 D20 Name: C600/X79 series chipset High Definition Audio Controller (Patsburg) 8086: 0 C0C Name: Xeon E3-1200 v3/ 4 th Gen Core Processor HD Audio Controller (Haswell) 8086: 0 A0C Name: Haswell-ULT HD Audio Controller.
Required
These two kexts you should always have in your EFI partition.
FakeSMC.kext – Mantatory kext that emulates a Mac and is required to boot a hackintosh. When you download FakeSMC the folder will also contain Sensor kexts that you can use to monitor your hackintosh read about that here : HWMonitor Sensor Guide
Lilu.kext – Arbitrary kext that is required other kexts to work like AppleALC.kext & NvidiaGraphicsFixup.kext. Some Gigabyte motherboards have trouble with some versions of Lilu.kext breaking audio. I recommend those users use v1.0.0, instead of the latest version.
USB
Downloads For Chipsets - Drivers & Software
USBInjectAll.kext – Injects all USB ports
XHCI-200-series-injector.kext – Enables USB 3 device detection and USB 3 speeds on Kaby Lake motherboards. This kext is also recommended to have during the macOS install process so you can use those USB 3 ports and flash drives.
Ethernet
IntelMausiEthernet.kext – Enables ethernet for motherboards using an Intel Ethernet Chipset.
RealtekRTL8111.kext – Enables ethernet for motherboards using a Realtek Ethernet Chipset
CirrusAudioXP_Macbook_c.zip1.0.0.13c (Nov. 1, 2009). Try This If Recording Still Fails With 1.0.0.13b, But It Probably Won't Help.
AtherosE2200Ethernet.kext – Enables ethernet for motherboards using Killer Lan Ethernet Chipset
Graphics
NvidiaGraphicsFixup.kext – Allows the latest Mac SMBIOS definitions to be used like iMac 17,x and iMac 18,x. You would want to use these SMBIOS defintions if you are using a Skylake or Kabylake CPU respectively. Updating to the latest version may fix black screen issues.
IntelGraphicsFixup.kext – Fixes display and graphical issues when using integrated graphics. I also recommend setting DVMT Pre-Allocated to 128M or higher in BIOS if using the Intel iGPU to enable high resolution displays.
WhateverGreen.kext – Enables AMD graphic cards in macOS 10.12.6 or later. Will require Lilu.kext. Read about it here : How to hackintosh AMD graphics cards in Sierra 10.12.6+
Shiki.kext – Protects against graphical issues with video playback
Audio
AppleALC.kext – Enables audio on a hackintosh. Read about how to enable audio here: Hackintosh Audio Guide. Some gigabyte users have problems with AppleALC.kext not enabling audio. I recommend them using v1.1.0, instead of the latest version.
HDMIAudio.kext – May help enable HDMI audio on some graphic cards. Read about it here : Hackintosh HDMI Audio + DisplayPort GFX Card Sound Guide
CodecCommander.kext – Fixes a problem with dim sounding or lower volume audio after sleeping/botting the hackintosh by updating EAPD (External Amplifier) state on HDA.
Spoofs

FAKEPCIID.kext – Enables support for Intel processors on earlier versions of macOS that don’t support that processor by pretending to be a supported processor. Kaby Lake CPU’s are nativily supported as of macOS 10.12.6
FakePCIID_Intel_HD_Graphics.kext – Enables integrated graphics on iGPU’s that are not supported in macOS by mimicking another supported iGPU. Kaby Lake CPU’s with HD 630 are supported nativily in 10.12.6. If you have upgraded to 10.12.6 you can remove this kext.
NullCPUPowerManagement.kext – Used to enabled hackintosh support for Pentium Processors like the G4560
