    'Unable to start the Dolby Audio Driver' - (Acer Aspire)


    Hi guys, I'm having an (what appears to be quite a common) issue with my sound since installing to Windows 8.1

    I have an Acer Aspire V3-571G laptop, and was recently asked to upgrade to Windows 8.1.

    Once I did that, a pop-up has come up saying:
    ---------------------------------------------------------
    Dolby Home Theater
    Unable to start the Dolby audio driver. Please restart the computer or
    reinstall the driver if the problem persists.
    ---------------------------------------------------------

    The audio for all my media players now refuse to work, while, say, Youtube appears to work fine.

    I've seen a few proposed solutions for this issue (including deleting, uninstalling and reinstalling of certain things), but most appear to be 'Lenovo' laptops. So basically I have a fear of deleting something wrong or doing some irreversible damage to my sound, since it may not be specific to my Acer Aspire.

    If anyone could give me a hand with how to solve this, that would be VERY much appreciated, as I am clearly not very tech savvy.

    Thanks guys and girls!

    Welcome to the forum!

    In your programs list you should have Acer Recovery Management. From there select Reinstall Drivers or Applications, then find Audio Codec and select.

    Thanks Popeye!

    I found the Acer Recovery Management folder, but couldn't find anything else you've said within it.

    I attached a printscreen so you can see what I mean. (they don't appear to be in any of those 'Helpfiles'.

    And also thanks for replying.

    No, you should find the program in your programs menu. Don't go to the folder. When you click on it should get something like this:

    Click image for larger version

    Can try clicking on that Recovery UI executeable.

    Clicking on that eRecoveryUI executeable in the folder should work also.

    I did the first option you stated. It appeared to uninstall and install my Audio Codec (which was 'Realtek High Definition Audio).

    Now I have no volume button on my bottom right-hand corner, and when I check my 'volume mixer', it says 'no audio device is installed.'

    I'm assuming there's a very simple step I'm missing to kick-start everything?

    -----------------

    I went into Sound and clicked on the 'Properties' of my
    Speakers
    Realtek High Definition Audio
    Default Device

    and there's a 'Dolby' tab - when I go to it, there's a pop up:
    ----------------------
    ERROR
    Error opening registry keys. Please verify registry key permissions.
    Run RegDolby.bat from the driver folder to change.
    ----------------------

    Would this be the next step?

    I would uninstall the audio device in Device Manager and select delete the driver if an option, run CCleaner (twice) on the registry. reboot and install the drivers from Acer Recovery.

    Did the laptop come with 8 or 8.1?

    The laptop came with Windows 8, and I was just asked to update to 8.1 the other day.

I updated to 8.1 because supposedly, it was to offer features similar to win 7. Instead, it's even worse than win 8. Now, the sound quality on my laptop is lousy because the Dolby Audio driver receives an error message and isn't working. I went to Lenovo (I have a Ideapad N Series 580) and...
