Windows 8 system can not open Dolby sound solution

The Dolby driver can't control the audio, and the win8 audio is still controlled by its own driver. After half an hour of perseverance, I found a new way to install Dolby Drive. I will share it. (After installing the official driver, the friend who turns on Dolby sound by default can ignore this sticker. This sticker is suitable for the official sound card driver. Friends than sound effects, if there is no pcee4 folder in the official driver package or do not find the Dolby installation file, please do not try to install)

1. Download the official sound card driver, such as the realtek driver I downloaded on the acer official website ( Do not use the driver update software to download the driver. It must be the official driver. Some brand machines must use the earlier official realtek driver to install the Dolby sound plug-in.

2 Uninstall the installed sound card driver

3 After rebooting, follow the steps to install the official driver. Please do not restart after the installation. Pay attention to the folder in the official driver compression package. There is a pcee4 folder inside. Open the Dolby sound plugin, find DolbyAdvancedAudio, run Installation

4 After the reboot, there is Dolby sound, and it is completely controlled (if you find the Dolby plugin after rebooting) Failed, please fix the installation of Dolby plugin.

Once again, my acer does not have Dolby sound. I have not found the Dolby label in the box and the body label. After installing this method, I can Turn on Dolby sound.
