hi Adam,


Welcome to the Lenovo Forums.


Can you try the following:

1. Uninstall Conexant HD Audio and Dolby Advanced Audio v2 (if applicable) under the Control Panel > Programs

2. Reboot the PC and re-install the Conexant Audio Driver for Windows 8.1 (this contains the sound driver+dolby)


Conexant Audio Driver   

      Windows 8.1  (32-bit, 64-bit)

After installing, reboot the PC and observe.
As for Battlefield 3, have you tried running the game in compatibility mode? If you're getting Direct-X errors, check this thread.

Once new driver is installed and Dolby comes back, the actuall interface is different than before in a bad way. If there any solutions to that, please reply. Thanks
