Dolby Home Theater v4 Not Working on Windows 10

Hi. Can you help me what to do to make my Dolby operational again after upgrading my Ideapad U310 to Windows 10? I had done several troubleshootings alreay like restarting my PC, uninstalling Dolby and install again but still it is not working. Thank you

Hi all
Could you try out DAA or DHTLightweight from my link and just install the Dolby software without overriding your Realtek Driver? I am not sure whether would it work, but worth a try. I have tried on Y460, W520 and G560 with great experience.
If the older Dolby software does not work with your existing Realtek driver, you could install the DAA or DHTLightweight with their driver to overwrite and see how it goes.
Thank You
Peter

Dolby Home Theater v4 not working on Thinkpad Edge E531

After updating to Windows 10, Dolby Home Theater V4 stopped working on my E531 Thinkpad laptop. I tried uninstalling the old version and reinstalling the latest version. No improvement. The sound is not as good as before now. Please fix this asap.

Dolby Home Theater v4 not working after upgrading to Windows 10

Hi there, I just upgraded to Wndows 10 Home from Windows 8.1; everything went smoothly except for the fact that Dolby Home Theater v4 does not work. I had to reinstall it using the .msi file found in the Realtek Audi folders. I chose v4 over any of the other versions because I like how I can tune the equalizer to my liking and different uses. Anyways, the regular audio works and Dolby is turned on but there is no activity appearing on the equalizer and my music does not change once adjusted. Had this problem when doing an optional audio driver update in the past when I was running 8.1. I do not have the option to rollback the driver after upgrading to Windows 10. Does anyone have a solution to this issue or know what the correct Realtek driver is to make Dolby work? This is one of my favorite features of my laptop and I really want it up and running again! Thank you in advance! JakeStiebs My unit: Lenovo Ideapad Z580 running Windows 10 Home with Realtek Audio Driver 6.0.1.7535

one more thing. I was not able to download cleanup tool/online scanner too. but may be it has something to do with my internet bandwidth. and other strange thing i observed is that before restart i was not even able to turn off all security features. but after restart that problem seems to be corrected.

Dolby Home Theatre v4 not working with windows 8.1

Hello,
I have recently downloaded and updated my laptop to windows 8.1 and suddenly dolby home theatre v4 has stopped working. Battlefield 3 has also begun to crash randomly. Could you please help me?

hi Adam,
Welcome to the Lenovo Forums.
Can you try the following:
1. Uninstall Conexant HD Audio and Dolby Advanced Audio v2 (if applicable) under the Control Panel > Programs
2. Reboot the PC and re-install the Conexant Audio Driver for Windows 8.1 (this contains the sound driver+dolby)
Conexant Audio Driver
      Windows 8.1  (32-bit, 64-bit)
     Version 8.65.3.53
After installing, reboot the PC and observe.
As for Battlefield 3, have you tried running the game in compatibility mode? If you're getting Direct-X errors, check this thread.
Regards

ITunes 9 Home Sharing does not work on Windows 7 x64

iTunes 9 Home Sharing does not work on Windows 7 x64.
Getting the following error message:
Home sharing could not be activated because this computer is not authorized for the account "iTunes account." Please authorize this computer and try again.
This is a bug since my computer is authorized in iTunes and there is only 2 computer authorized for my iTunes account, so I have 3 more left till I should get this message.
I've just upgraded my iPhone to OS 3.1 using it this morning.
Please advise.
Environment: Windows 7 x64, HP TouchSmart tx2-1020us Notebook

I am using Windows 7 x64.
I am running iTunes 9.0.2.25
I am running Mcafee.
I can see and play music from the iTunes installation on my Windows 7 machine, but I CANNOT access the library to copy songs from this computer to other computers on my network.
YES, I have enabled "Home Sharing" using my iTunes account. NO, I have not authorized more than 5 computers on this account.
I believe this to be a Windows 7 related issue, as Home Sharing worked as advertised when I was using Vista (before I upgraded to Windows 7).
I CAN set up Home Sharing on two other (host) computers in my home network and it works. These computers are XP and a MacBook Pro. I CANNOT access my Windows 7 machine x64 to COPY music from one autorized library to another. Please help!!!
P.S. - I have attempted to get this to work by turning OFF my McAfee firewall. Windows firewall is disabled.

Dolby Home Theater v4 Not Found

I am having problems with Dolby Home Theater v4 when I installed the Windows 8.1 update. The program can run, but it doesn't give any response. When I am playing music or do any other thing with sound, it makes no difference. What should I do?
Specifications:
Windows 8.1 64-bit Operating System, x64-based processor
Lenovo Ideapad U530
Processor: Intel(R) Core(TM) i7-4500U CPU @ .80 GHz
RAM: 8.00 GB
Above the Intelligent equalizer, there is supposed to be a 20 bands spectral modifier and visualiser.
How do I fix this?

More often than not when a device isn't working it is because the driver has become corrupted. Re-installing a fresh copy should help

Dolby Home Theater/Dolby Digital Plus not working

Update: Issue gone today. Dolby working properly. Still using same drivers. (Win 10 64-bit). How? I don't even know. edit: I think turning off "Hey Cortana" fixed it for me.

MattSharp ha escrito:
Dolby Digital Plus has miraculously started working, though it looks very different to the last time I used it (it used to be a lot smaller and said Home Theater rather than Digital Plus) but its better than nothing.Hi, 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 V5-552G 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

Dolby Home Theater V4 changed to Dolby Digital Plus after Realtek Audio Driver update Windows 8.1

Hi,I'm now using Ideapad Z510. After upgraded to Windows 8.1. I'd went to the Lenovo website searching for new driver update.
But, after i install the "Realtek Audio Driver 6.0.1.7023", the "Dolby Home Theater V4" is not running(audio sound not playing through).And, the "Dolby Digital Plus" is running instead of "Dolby Home Theater V4".
Then, when I try to reinstall the older version "Realtek Audio Driver 6.0.1.6954" from Lenovo website, the "Dolby Home Theater V4" is running again.
Truly, the "Dolby Digital Plus"'s sound is crisper and louder than "Dolby Home Theater V4". But the sound of "Dolby Home Theater V4" has more bass and more function (like Graphic Equalizer, more Intelligent Equalizer etc.).
Is this an update or what?
What should I choose?The newer driver (for Windows 8.1) or older driver (for Dolby Home Theater V4)? Thanks. (confused now) @@

Hi all
Could you try out DAA or DHTLightweight from my link and just install the Dolby software without overriding your Realtek Driver? I am not sure whether would it work, but worth a try. I have tried on Y460, W520 and G560 with great experience.

Can't install Dolby Home Theater after upgrading to windows 10

HI, I have an Acer v3 572g. I upgraded from win 8.1 to win 10. Everything is working fine except that the upgrading process completely removed the Dolby Home Theatre application and its drivers and automatically installed the Realtek high definition drivers, after I found out about it, I tried some tips I found online , this is what I did: Downloaded the audio drivers from the Acer website, uninstalled the default audio drivers then, I installed the acer drivers followed the installation process restarted my computer after that, I try to run the DolbyHomeTheater installer found in the PCEE4 folder but after I open the setup file it says: DHT cannot be installed. it doesn't explain why it cannot be installed whatsoever. I can't get this app installed no matter what I do, I've tried different things like installing and uninstalling multiple times, running the setup in compability mode... I don't know what to do now Any help will be very appreciated.

Hi! Thanks for your reply, I did exactly what you suggested but it didn't work for me. I'm able to install the audio drivers but when I try to run the Dolby Home Theater setup, it gives the same error "DHT cannot be installed" I now tried running the setup in troubleshoot compability mode it says: "Settings applied: Windows compability mode: Skip version check.Then, I click on test program but get the "DHT cannot be installed" error.After that, Windows compabilty troubleshoot asks me whether the problem is fixed or not, I click "no" then it says: "issues found: Incompatible program: DolbyHomeTheater is incompatible." But the odd thing is I'm able to install Dolby Advanced Audio v2 and not DHT v4,
I don't know if this is an issue with Windows 10 and Dolby, Acer or both are working on it or something went wrong during the upgrading process...

V5-552P Windows 10 audio driver got rid of Dolby Home Theater

A few days ago I upgraded my laptop to Windows 10 and everything worked fine, including Dolby Home Theater. However, today I decided to install the Windows 10 audio drivers for my laptop on Acer's website just to make sure they were fully updated, but now Dolby Home Theater is completely gone from my system. Why does the Windows 10 audio driver get rid of Dolby Home Theater and how can I get it back?

try to install this drivers:http://station-drivers.com/index.php/downloads/func-startdown/1591/ 100% trustable websitedouble click on exe, on the extracted folder look for setup.exe file and run it.

Better privecy does not work with windows vista home prem. what other program removes LSO'S AND HOW can I stop trackers?

Question
better privacy does not work with windows vista home prem. what other program removes LSO'S AND HOW can I stop trackers? edit
Details

As a temporary workaround, I believe this Adobe management page allows you to clear your "Flash cookies": [http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager07.html Adobe - Flash Player : Settings Manager - Website Storage Settings panel] (hosted on macromedia.com -- Macromedia was the original developer of Flash).
Regarding the script error, if I'm reading the script correctly, it is related to accessing your Flash cookies directory. It seems the publisher's support forum is not currently available for searching, but that might be a good next step.
In the meantime, could you check whether the script has the correct location for your Flash cookies directory? If you can't access Tool > BetterPrivacy, you could check here:
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the filter box, type or paste '''bpr''' and pause while the list is filtered
(3) There should be a bolded setting named '''extensions.bprivacy.DataDir''' which looks approximately like the following:
C:\Users\''yourWindowsUsername''\AppData\Roaming\Macromedia
Do you have a similar value? If you paste the path used by BetterPrivacy into a Windows Explorer window, does it open? Also, click a couple levels in the folder, can you see:
Flash Player \ #SharedObjects
If the value is wrong, right-click the wrong value and choose Reset. BetterPrivacy should update the value the next time you try to access it.
If the value is blank, you could try inserting a sensible value and see whether that helps.
Any luck?

ITunes Home Sharing not working in Windows 8 with Apple TV

My Home Sharing does not work on Apple TV 2 - I am running the latest version of itunes, apple tv software, all windows updates installed, all firewall ports required are open, anti-virus is allowing things through, I have reset and restarted my apple tv, pc and routers, unticked IPv6 - still nothing - please help!

Problem solved, however not the way I would have preferred...
Turns out that I needed to disconnect the hardwired ethernet connection between my router and the Apple TV.
I my setup consisted of a traditional hardwired Linksys router, and a matching Linksys access point.
Both my computers were on the wireless network setup by the access point, and were able to communicate between each other just fine.
However, for whatever reason neither one would communicate with the AppleTV while it was hardwired to the router. Once I unplugged it, and assigned it to the same wireless network as the computers were on, it was able to see both computers without any problems...
Not too upset, seeing as how the AppleTV is only about a foot from the access point and router - so there are no signal strength issues. However, I would have preferred to keep the AppleTV on the hardwired connection...
Hope this comes in handy for anyone else with this problem...

Hi,
It might be the graphic driver not compitable with the graphic device. Has there been a change to the graphic driver?
One thing you can try is to uninstall graphic driver and download the latest from Windows Update (if you haven't tried this). Here are the possible steps:
1. Go to Control Panel->Hardware and Sound->Device Manager, uninstall the graphic card driver by right clicking and select "uninstall". Make sure the option "Delete the driver software for this device" is selected.
2. Reboot the system.
3. Go to Control Panel->System and Security->Windows Update, click on "Optional updates" and find the driver for g210 and do the update.
