The chdaud.sys process is a system driver file that is used and referenced by the Microsoft UAA Function Driver for High Definition Audio Service module, which is an applet built into the firmware distributions and driver software packages that are bundled with certain audio chipsets and devices from Conexant Systems. In order for the associated Conexant audio chipset and device to properly perform its embedded functionalities and implement its integrated features into the Windows-based system upon user request, the chdaud.sys driver file works with other SYS driver utilities, executable process items, modular DLL (Dynamic Link Library) components, specific background and system processes among other resources that are used and referenced by the Conexant firmware distributions and driver software packages of the corresponding audio device and chipset. The chdaud.sys file is placed in the system upon the installation and configuration of these Conexant firmware resources and driver software components, which also means the chdaud.sys process is packaged into the installer distributions of these Conexant audio device driver software components and audio chipset firmware resources.
