Go to Solution.

hi shanalikhan,
The error on the screenshot that you posted usually happens if the version of the audio driver and the dolby digital driver are different. Both of them must use the same driver in order for them to work correctly.
Try to:
1. Press the Windows key‌ +R, type appwiz.cpl.msc and press Enter. On the list of installed programs, remove anything that relates toRealtek Audio Driver and Dolby (reboot if necessary).
2. Delete the C:\Drivers folder Install this audio driver (windows 8 version).
Audio Driver (Conexant, Realtek) for 64-bit Windows
3. Open Device Manager > Sound, video, and game controllers and check if the High Definition Audio becomes Realtek High Definition Audio or Conexant High Definition Audio (this indicates that the sound driver is installed properly).
When the audio driver is properly installed, install the DolbyAdvancedAudio and the DolbyHomeTheater from the following path:
For Realtek:
C:\Drivers\Audio\Realtek\6.0.1.6957\PCEE4
For Conexant:
C:\Drivers\Audio\Conexant\8.64.49.0\DolbyGUI
- Link to picture
More info:
Dolby Audio driver cannot start after upgrading to Windows 8.1
Let me know how it goes.
Regards

  • I can't remove Firefox 8 from control panel?

    I update Firefox8 to 9.1, but upon looking in control panel still said I had Firefox 8. Also, I had automatic update enabled and it never updated, so I therefore put it to manual. I was having Java issues that weren't resolved with Firefox and have decided to uninstall! I am unable to from control panel or uninstaller? When I click remove it does nothing but go bk to original state like I never clicked remove. All other programs are removable from this feature! I don't understand why I am being refused the option to remove, in the meantime I have blocked access. Thank you for any assistance in this matter.

    Version 9.1 auto loaded on my computer and I had problems. If 8 is working, don't go to 9.1. I spent hours trying to find an earlier version and the best I could do is find 6.0. I downloaded it and my problems were corrected. I recommend you keep 8.

  • Uninstalled epson printer from control panel...installed new brother printer....now i cannot print anything .pdf old or newly downloaded

    uninstalled epson printer from control panel...installed new brother printer....now i cannot print anything .pdf old or newly downloaded@

    For starters, what exactly do you mean by "cannot print"?
    Are you getting an error message? Are you trying to print from within Reader or are you opening these in the browser? What version of Reader. Even though it's a new printer, the drivers that came with it (or the ones that were already on your computer) may be old so, have you downloaded the most recent drivers from the Brother site?

  • We try to unistall from control panel or helper folder and nothing happens. What are the next step.

    We want to upgrade Mozila to a new version. When we try to upgrade from your web site, nothing happens.
    When we follow your recommendation to unistall the program from control panel or helper folder, the folder doesn't open.
    we need to force the unistall to upgrade the new version.
    Thanks for your advice.

    I had the same issue. To resolve it, I:
    1. Backed up my bookmarks to my desktop;
    2. Deleted the Mozilla Firefox folder (in the C:\Program Files folder).
    3. Reinstalled Firefox
    4. Uninstalled Firefox (to make sure any registry entries that may have been causing problems were removed)
    5. Reinstalled Firefox again
    6. Imported bookmarks.
    7. OPTIONAL: Reinstall any add-ons I regularly use
    I no longer have the problems with slow performance or websites hanging that I had after originally upgrading to Firefox 7.
    Obviously if you just want to uninstall, you only need to do steps 2 through 4. I wanted to continue using Firefox and was just trying to resolve the issues I was having browsing the web since upgrading to 7.

    This could be a Launch Services issue. The following article describes how to manually reset Launch Services — the notes at the bottom of the article also provide information about the side effects of deleting each of the files involved:
    Resetting Launch Services
    If you prefer using a cache cleaning utility instead of following the manual procedure described in the previous article, take a look at this other article for general troubleshooting and cache-cleaning procedures. Actually, you should also verify/repair the startup disk (not just permissions), as described there:
    Resolving Disk, Permission, and Cache Corruption
    The most appropriate utility for this particular problem probably is Tiger Cache Cleaner, but you may also want to consider other utilities, such as OnyX, or Cache Out X, which are free. Whatever utility you choose, be sure to read this first:
    Side effects of System cache cleaning
    As an example, this is how you should proceed with OnyX:
    1. Quit all applications.
    2. Launch OnyX and enter your administrator password.
    3. Go to Maintenance > Reset and check LaunchServices database.
    4. Un-check any other pre-checked options.
    5. Click the Execute button.
    6. Restart the computer.
    BTW, if you’re running Mac OS X 10.4 (Tiger), as your profile indicates, it would have been more appropriate to discuss this in the Mail & Address Book - Tiger forum. If the discussion applies to both Mail 1.x and Mail 2.x, it doesn’t really matter, but it’s difficult to know that in advance.

  • TS3276 i am unable to open web pages from email links on my ipad

    I am unable to open web pages from email links on my ipad

    A few more details might help, if nobody else recognizes this.   
    What happens when you try to open the links?
    Can you post an example of a link that doesn't work?
    Is there any particular source for the mail with the (bad) links, or is mail from all sources failing?
    If you happen to know it, what's the format of the mail message?  (Maybe the message is an image?)
    Do the embedded links work as expected from an OS X system running Mail.app, or some system and some other other mail client?
    To view the link in iOS: if you press on and hold your finger on an embedded link in most contexts, iOS will show a pop-up with the link contents, and will offer to copy it.  You can use that to acquire and post the link.  If pressing and holding on the link doesn't offer the pop-up, the format of the link itself may not be valid, or it might not really be a link.

  • Unable to open Information Map from planning web Help menu

    Unable to open Information Map from planning web Help menu
    The error is :
    Error 404--Not Found
    From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
    10.4.5 404 Not Found
    The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
    If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.

    Hi,
    It should be accessing :- http://<planning server>:8300/HyperionPlanning/help/en/hp_information_map/hp_information_map.html
    Can you access that address on the machine hosting planning?
    The file structure on the web server depending on which app server you use should be something like \Hyperion\deployments\Tomcat5\HyperionPlanning\webapps\HyperionPlanning\help\en\hp_information_map\hp_information_map.html

    Hi,
    I check this issue in my environment, but cannot repro this issue.
    Please check the following path to click the right cpl file:
    C:\Program Files (x86)\Microsoft Office\Office15\MLCFG32.CPL
    If that works, you need check this registry path to see if it points a right path to the .cpl file:
    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Control Panel\Cpls

    Never mind, I think. I think I figured it out. There was 1 song (out of > 900!) that somehow had been purchased with the other ID - I have no idea how. Once I deleted that song, it stopped asking.
    There may be something with the newest iTunes version too. I didn't think in older versions that the "On this iPod" list of songs was greyed out. But at least it syncs ok.

  • Windows Update from COntrol Panel does not work??

    Hello,
    regardless if it is common way to do so or not: Does anyone have experience with the "Windows Update" functions in WE8S?
    I tried them upon a customers request, and I've seen that I could not get it to complete successfully when choosing the option in
    Control Panel. It either hanged during "Downloading..." or at the "Preparing to install..." screen - I waited for many hours. But when I using the "Windows Update"
    app from the start screen, updates were installed without any problems (OK, 1 has failed, but the process has completed). Of course, both methods have different look, maybe it is not the
    same...
    As per Sean Limings' book it is no good idea to update systems in the field this way - shall I remove the functions from the system? What are you doing?
    Thanks,
    Willi K.

    Maybe it was because of the number of updates (in my case there were 85 updates pending). After I succeeded installing via the "Windows Update" app from "Start Menu", there where two more updates, and update now worked when called from
    control panel (at least one of them, KB2973201 still stolidly fails to install).

  • Backup from ThinkVanta​ge R&R or from Control Panel Backup?

    Should one backup from

    Pluses and minuses for each?
    Thanks.

    wjli2,
    Is there a way to reinstall only R&R from the restore CDs.  I am thinking about uninstalling it, since it is worthless in its current state.  How long should it take to backup the 64GB SSD to an external USB drive?
    Thanks, Faz
