I've got y580 and without DHT music sounds a lot better, but I miss the old Realtek's equalizer. With DHT sounds are like in phone earpiece. Any advices how can I restore old equalizer or fix DHT?

Thanks for posting!
You should be able to create or customize the DHT Equalizer for fine tuning
If you are not able to access the custom settings
Follow this steps to reinstall DHT with audio driver
For us to make a Clean and proper install, Follow this guide
1. Uninstall the Conexant Driver from device manager place a check under "delete device software" and any Dolby related from your Control Panel / Programs and features / Uninstall a program. Then Restart the system
2. Download the Conexant Audio drivers from support.lenovo.com . Install that and complete everything. Restart.
3. Go to My Computer /> C: (C Drive) /> Drivers /> Conexant Audio Driver /> DolbyGUI

So I should install Conexant instead of Realtek? Also Realtek drivers from support aren't up-to-date and DHT doesn't work with them, but it works with newest from Realtek site.
Indeed, it works with R2.70 Realtek drivers, but still the sound, even on user profile, is flat, there's almost no bass and EQ work really bad.

It really depends on your Audio Hardware. If you have realtek HD Audio then that's the one you need to download and install.
But the Idea here is that.
The Dolby version should match the Audio driver.
The Audio Driver from support.lenovo.com contains a bundled DOLBY Installer, after installing that to your computer will extract a DOLBY compatible installer to your C: Drive, that's why the audio driver from support site is too big in size.
Just have to locate where it extracted and install that.
AFAIK these is where it will go, after installing your audio driver check these directories and see if there will be a DOLBy Installer.
C: /> Drivers /> Conexant Audio Driver /> DolbyGUI
C:" /Drivers /Realtek Audio Driver /PCEE4
Installing a mismatch Audio driver and dolby may cause version error

There's no such a thing in Realtek's folder. And it weights about 4 mb more than newer version from Realtek's site, but it may be caused by the executable archive that unpacks drivers to drivers folder.

if you'll check this link for your system's driver download
Realtek driver for WIN 7, 8 and XP has the size of 83MB 116MB and 122MB.
It should extract/create a "drivers" folder on your C: Drive and contain following folders i posted above.
also please see these threads about Audio driver and Dolby integration.
Let me know your findings

That's how my Realtek folder looks like. I'll try to experiment with different drivers (like for XP, or R2.71 from Realtek's site). Could you tell me if you have any experience with sound with and without DHT? Does it's EQ is at least as good as old Realtek's one?
08-06-2013 03:12 PM
Yes, DHT and the Realtek EQ both has Multi Band controls that let's you fine tune the audio
Are you using the driver from the Realtek website?, that may be the reason why you dont have the folder for Dolby.
I would suggest doing this and I'm sure you'll have DHT Back.
Make sure to un-install the Audio driver first under Device Manager
> Open device Manager
> Go to sound, video and game controllers
> Look for Realtek High Definition Audio / High Definition Audio
> Right click on it and select uninstall put a check on Delete the driver software for this device
Check you Control Panel / Programs and feature / Uninstall a program list for any Realtek Audio and any DOLBY APP.
If non then just proceed to the next step,
Download and install this
After installation go to Your Drive "C:" under My Computer then go to
/Realtek Audio Driver
You should find the DHT installer there
After that you should have the Dolby EQ Settings,Best Regards
Thanks and Best Regards

There's the catch. That's the Realtek driver from lenovo site, I have DHT, but it sounds just awfull.
That's how it looks.
And that's how it sounds.

I see, that's a really big difference,
Have you tried adjusting it to through the custom EQ settings/
Go to Control Panel, Im sure you'll find a Dolby icon there to access the settings.
Thanks and Regards
