Which of the guides on the sidebar you used: Opencore 0.6.3 https://dortania.github.io/OpenCore-Install-Guide/extras/big-sur/#table-of-contents

What's working: WIFI/BT,Continuity & iCloud services.

and what isn't working: Audio,Trackpad,Camera input,Battery indication,Keyboard controls for Brightness.

I've tried all layout id's alcid=xx for my codec as mentioned on

https://github.com/acidanthera/AppleALC/wiki/Supported-codecs.

No sound is shown in output.

For Battery patching as per Rehabmans guide, https://www.tonymacx86.com/threads/guide-patching-laptop-dsdt-ssdts.152573/

I've decompiled the DSDT.aml and tried to use Acidanthera: MaciASL for patching using https://github.com/RehabMan/Laptop-DSDT-Patch/blob/master/battery/battery_HP-Envy-17t.txt

The above however generates an error.

Prior to using OC 0.6.3 I have been using this laptop for 7 years on OSX using Rehabmans Guide(Mavericks~Mojave) : https://www.tonymacx86.com/threads/guide-hp-envy-haswell-series-j-k-q-n-using-clover-uefi.261724/

Intention is to now transition away from Clover to OC provided I'm able to get the same installation and functionality.

Any troubleshooting or link sharing will be much appreciated.
