When I click on the DBT icon on the tray, usually it brings up 3 profile which is film, music & game. But today, it does not work. whenever I have I turn it on, there is no change in sound at all (volume, bass, pitch, etc.). even the equalizer slider made no change on the sound produced by the speaker. I don't test it on my helmet, speaker external and theres no change. but the noise is always present and no change to dolby. can someone provide me with a solution?

    Thank you and sorry for the bad language, I have trouble typing in English.

  • Windows 10 Dolby Home Theater V4 does not

    On my Lenovo Edge 15 (BestBuy exclusive model), I've recently upgraded to Windows 10 and found that the Dolby Home Theater V4 software does not work. I tried to uninstall and reinstall the drivers and software and still cannot program to work. The program opens and displays options, but Equalizer does not move (as it was on Windows 8.1) and it doesn't have a difference in the audio output.

    All of this worked before my Windows 10 transition. The audio quality is very thin and hard to hear without this software, I hope someone has a solution. Thank you very much for your help!

    Nice day.

    Please see Section 3 - limits of Application, from: https://support.lenovo.com/us/en/documents/ht103611
    Dolby Home Theater is not supported / not functional on Windows 10, for compatibility reasons.
    The official recommendation is to first uninstall it before upgrading to Windows 10.

    Hope this helps to clarify.
    Kind regards.

  • Satellite A200-10N (PSAE3): Fn key does not work after upgrade to vista any time

    After upgrading Vista-Home - Premium--> Vista Ultimate shortcut with the fn keys does not work, for example Fn + F6/7 (brightness).

    New value pack installation has not been successful.
    Moreover, after upgrading the drive to DVD from Toshiba is default, too.
    Who can help?

    I didn't try any update on my A200 but you can try to follow: install Vista using recovery media delivered. When Vista starts for the first time go in Panel and you can find Add/Remove Programs option. Remove all the stuff designed by Toshiba.

    When we remove everything, making Vista upgrade. After finishing Vista upgrade install all the stuff of Toshiba designed by order of specific facilities starting with added value package. Check please the download page if all of these tools and utilities are available.

    As far as I know all the tools and utilities are designed as universal tools and I can't imagine that there is a difference between the version of Vista ultimate or premium tools.

    DVD player is part of the image of the installations only and I can imagine that upgrade installation has changed something, but the upgrade procedure is responsible for this. I don't see any connection to Toshiba.

    As I said I don't have a CD to upgrade, but if I find one I'll try to test it on my Vista (Premium) preinstalled A200-1CR.

    Bye and I hope that you report your experiences with the Vista upgrade again.

    Install the VAP (value added package) and reboot the laptop.

    Then install the Support Flash Card utility and reboot once more.
    Then test the Fn keys.

    The buttons are controlled by Flash cards, so you should be able to use the buttons after a new installation of this app.
