The v4's installer (exe) is in the zipped folder, but digital plus is what installs. The Dolby software is 'Dolby Digital Plus' and Not 'Home Theatre v4' Then with the internet still off, install the windows 10 drivers and viola ! Install your windows 8.1 drivers, that should install and dolby should be there. Also uninstall your realtek drivers from the control panels 'Programs and Features'. Uniinstall your drivers (audio) from the device manager. If all goes well you should have a dolby application in your system tray. Step 3: Now open the installer for the audio driver (Windows 10 first), follow the prompts etc, Download Windows 8.1 (A01) audio driver just in case. Step 1: Download latest Windows 10 driver (audio) Thankfully, I was able to find a solution online : )Ĭredit should go to the guys on the forums of Notebook Review (If anyone's interested - I can post the link).
