The Intel DZ77BH-55K has Dobly Home Theater v4 support, however the only user interface available to it is to switch it on/off and change between the three modes (musci/video/gaming). My Acer laptop also has Dobly Home Theater v4 and has a tray icon which allows the changing of the previously mentioned options as well as a settings page. The settings page allows the equalizer for each mode to be adjusted as well as the volume leveler/surround virtualizer/dialogue enhancer etc. It would be really great if the Dobly Home Theater v4 settings application could be added to the audio driver installation as the current implementation is a bit crippled. This should be possible as it is an included module of Dobly Home Theater v4.
EDIT: For clarity this is the settings window which contains the features which are currently not usable:
This control panel exists on my laptop which also supports Dolby Home Theater v4.
in the sound control panel, you can find dolby home theater, there is an icon to turn it on/off, underneath you'll see the 3 modes, just click the mode you want.
