DZ77BH and some problems (unknown device, Dolby, Intel Desktop)

Hello ,

I've a new dz77bh-55k with a xenon-CPU and after installing all software three problems:

1. In the device manager there is an unknow device:
   PCI-Communicationscontroller (simple)
   VEN 8086
   DEV 1E3B
   SUBSYS 20408086
   Rev 04
   
   
2. I installed from CD the Dolby Home Theater, after updating the audio driver to the newest one I got a message:
   Currently installed is version 7.2.8000.13 of the Dolby-Audiodriver. The Software needs driverversion 7.2.7000.7.
   
   I don't find a way to get the new DHT.
3. From the Intel-CD I installed Intel Desktop Software Version 3-2-4-055
   I can start it, but it will stay searching for something. The tabs "Systeminformation", "Hardware-Monitor" and "Options" are grey, only Help is blue.

I use the newest driver, checked with Slimdrivers.

Where can I get the driver for the unknown device and a new DHT ?

Is Intel Desktop Software something like Speedfan ? If yes, then it doesn't matter with it, because I'm used to start Speefan every boot.

Thanks for any tipps.

Best regards from Germany
