    Dolby home theatre


    Since upgrading to Win 8.1 (from 7) I cannot get Dolby Home Theatre to load
    The sound card is part of the Gigabyte GA-X58A-UD3R Revision 2 motherboard -
    Realtek ALC889 codec
     High Definition Audio
     2/4/5.1/7.1-channel
     Support for Dolby® Home Theater

    I have tried loading the Realtek High Definition Audio driver 3.77 R2.72 which seems to install OK but when I then try installing the Dolby home theatre 4 GUI package it fails with a message saying PCEE needs to be installed.

    Help appreciated, thanks

    Did it come with the computer? On my laptop I have found that I have to use the Realtek drivers supplied by the manufacturer or else DHT breaks. I think they put some additional code in to interface with the Dolby.

    No, after the original install (using W7) I installed the DHT program separately from Gigabytes' web site.

    Also, I am not quite sure why I have 4 high definition audio devices ?

    Do they also have a Realtek driver on their site or is it a combined driver with both the Realtek and DHT? I would start from scratch and delete those multiple instances of HD audio then reboot and install whatever is on the Gigabyte site. As long as it is 8.1 compatible of course.

    I've tried deleting them from device manager but when I re-boot they all come back again

    Wish I knew. Never seen that many HD Audio Devices showing up. You don't have any other audio hardware or some kind of virtual audio device installed? Could it be due to that TV capture device? Have you tried removing/uninstalling it? Maybe the Life Cam also.

    Sorry, I'll have to concede to someone else who may jump in with other ideas.
