• This laptop comes with a Cirrus amplifier which needs some ACPI tables that are not present in the BIOS. Patches 03 and 04 add EXPERIMENTAL in-kernel hacks to configure the amp properly. Alternatively, you can add the missing ACPI tables to the bootloader, see acpi/ for instructions.
• Patch 01 contains fixes for ALSA:
  • Fixes subwoofer volume not being adjustable
  • Fixes Headset mic not being detected

• Connecting/disconnecting the charger causes kernel: asus_wmi: Unknown key code 0x7b errors in dmesg
• Connecting/disconnecting external USB-C display causes kernel: asus_wmi: Unknown key code 0xc0 errors in dmesg

Patch 02 silences both errors by ignoring those keys codes.
