If you want to update your sound driver, double click the file WDM_A404.exe without uninstalling the previously installed drivers. The new file will take care of the update and old files itself.
For fresh install, if your OS automatically detects the new hardware, cancel the automatic detection and then double click the new driver file WDM_A404.exe and follow the instructions. Reboot for new changes to take effect if it prompts to.
