DDP is not DHT, dolby provides a separate software for each and thats why it does not look the same.
I read on the net that DDP was not as good as DHT, but I don't know...

Anyway I´m on a V3-571G and I have had these problems before with a clean install of 8.1 and again this week with the upgrade to W10. Let me tell you what worked for me but before we begin just let me say that Dolby Home Theater has always given me problems and will sometimes just turn off and other times the icon in the taskbar would go away or just not respond. I´m hoping it's more consistant on W10 though I dont see why it would be.

The only driver that ever worked properly with Dolby was the driver for windows 8 (not 8.1). the new driver on the Acer site for winodws 10 did not work either. So the one I´m using and I´m listening music to with DHT while writing this is: Audio_Realtek_6.0.1.6878_W8x64_A

To get dolby to work:

1. Uninstall the current driver, and any software related to it (the dolby software)

2. restart

3. Install the driver for windows 8 (in my case it never installs dolby automatically, I´ll explain how to do it manually below)

4. Restart twice (yes, I always had to restart twice after the install otherwise manually installing dolby would not work and I got an error when trying to run the install)

5. In the driver folders you downloaded and unzipped go to the folder "PCEE4" and run "DolbyHomeTheater.msi"

6.If you dont get the "Install PCEE" error, restart and you should be able to enjoy dolby (when its not acting up). If you get the error then you may have not followed the instructions properly. Go back to step 1

Good luck guys

  A Powerful Multimedia Machine

  You watch movies and TV shows on your PC. You use it to stream music. It's your game console and your videoconferencing center. Yet your PC has one major flaw, and that's its sound—tinny and weak at lower volumes, buzzy and rattling when you crank it up. Dolby Home Theater v4 solves the problem of PC audio performance with a suite of technologies that finally make your PC sound like the powerful multimedia machine that it is.
  Dolby pioneered high-quality audio first in the recording studio and at the movies and then in the living room. Dolby Home Theater v4 benefits from decades of experience in areas like noise reduction, speaker optimization, and surround sound. It's a complete solution and improves audio performance whether you choose to listen through your PC's built-in speakers, your favorite pair of headphones, or by connecting your PC to a home theater system.
  
  
  
  
  
  

  The Challenge of PC Audio

  Understanding how Dolby Home Theater v4 works requires understanding the problems inherent in PC audio. These originate in both the quality of the source material and the playback process.
  Typical problems with sources include:
  
• Dull sound and unintelligible dialogue on user-generated content
• Wildly varying volume levels from one source to the next
• Content not produced in surround sound

The small speakers and underpowered amplifiers required to fit into the physical design of PCs create other problems. These include:

• Irregular frequency response with no highs or low

• • Unnatural, colored sound
  • Volume levels that are typically not loud enough
  • Distortion and annoying mechanical vibrations when sound is turned up
  
  
  
  
  
  
  
  

  The Dolby Home Theater v4 Solution

  Designed into a PC, Dolby Home Theater v4 first applies processing that fixes any problems with the source material. It then fixes playback issues by compensating for mechanical constraints of the PC itself.
  Because Dolby engineers custom-tune each PC model that includes Dolby Home Theater v4, the audio processing ensures that you enjoy optimal sound for the specific combination of speakers and amplifier in your PC.
  Dolby Home Theater v4 technologies:
  
• Use our latest and most advanced algorithms
• Draw on our extensive research into how people perceive sound
• Match human audio perception
• Are built on a common processing framework
• Work together intelligently
•
