Many users have found that the driver package exists but the installer setup file fails to run correctly. The driver files, however, are valid. You can force-install them.
The hardware ID refers to the Everest Semiconductor ES8336 (also known as the ESSX8336) low-power audio codec. This chip is commonly found in modern budget laptops and tablets, such as the Huawei Matebook series, Chuwi devices, and various Intel Gemini Lake or Tiger Lake platforms. acpi essx8336
In standard laptops, ACPI for audio follows the "Intel HDA" standard. However, the ESSX8336 uses the Simple Audio Bus (SoundWire or I²S), which relies on a different subsystem in the Linux kernel called . For ASoC to work, the ACPI tables must provide specific properties, such as: Many users have found that the driver package
This usually occurs after a clean install of Windows (Windows 10 or Windows 11) or a major feature update. Microsoft's generic driver library (Windows Update) does not natively include drivers for the ES8336 codec because it is a relatively niche chip used mostly by specific Chinese laptop OEMs. Without the specific driver, Windows knows something is there (via the ACPI ID) but doesn't know it is an audio device, so it classifies it as "Unknown." The hardware ID refers to the Everest Semiconductor
In the context of ACPI, a device with an ID like ESSX8336 would be managed through the ACPI interface, allowing the operating system to control and configure the device's power states, as well as other operational parameters.
