The current Dolby audio driver 7.2.8000.17 and the software application expects driver version 7.2.7000.4. please install a valid driver and software application combination.


I suspect Win10 is not compatible with your audio devices. Go and have a look on the Aspire web site and search for driver updates. If there are none, uninstall Win 10.

Missing plugin


First, check vendor's site. Are those head phones compatible with your version of Windoze?

If so, pull up hardware manager - check for conflicts. None? delete the current driver. Reboot. Do the headphones work?

If not, next step is to go to vendor's site and check for updated drivers. If there is one, install, reboot, check. Still no go?

Call the vendor: outline the steps you've taken, remind them that the headphones are compatible with your version of windows according to their documentation, and ask them how to fix the situation.

Good luck!

We hooked it up and have no sound


From the Console Settings screen in the System area of the Xbox Dashboard, you can configure the video output of your Xbox 360 console for a widescreen, high-definition TV, determine your audio options, and check your console's serial number and Xbox Dashboard version.
Go to correct section for ... Audio

Change your audio output settings for games from this screen. These audio settings do not affect DVD movie playback. For DVD audio settings, refer to an individual DVD movie's setup screen.

Settings consist of:

  • Analog Output Settings: choose Mono to merge the left and right audio signals so that you can hear all sound through a connection to a monaural TV or monitor; choose Dolby Pro Logic II to listen in normal stereo (no audio surround receiver required) or to listen to Dolby Pro Logic or Dolby Pro Logic II soundtracks from compatible games or other media.

    Dolby Pro Logic consists of four channels of audio: front left/center/right and a monaural surround channel that is mirrored in each of your rear left/right speakers. Dolby Pro Logic II uses digital signal processing to generate 5.0 audio (front left/center/right, rear left/right) from any stereo (left/right) programming, whether from movies, music, or games. Unlike movies and music, however, games are specially encoded with Dolby Pro Logic II decoding in mind.

    To listen in either Dolby Pro Logic or Dolby Pro Logic II surround sound, you must connect your cable's left/right (white/red) RCA connectors to a compatible surround receiver. For more information, see our connection page for the cable you're using:
  • Digital Output Settings: configure this setting only if you'll be using the Toslink optical digital-audio output from a compatible Xbox 360 AV cable (optical digital-audio cable sold separately):


    The default digital-audio setting is Dolby Digital 5.1. If this is your preference, you do not have to make a selection from this screen.

Not compatible with my current version of windows what do I need to do?


Not compatible or not working well with windows 7?
(making a program work with windows 7)

Maybe, It doesn't work because the driver/application you installed is for other versions of operating system. I am also using windows 7 like you so don't you worry, You can still use your old installer/driver from other versions of operating systems. Just remember that before installing any program in a windows 7 Operating System Computer, Use "troubleshoot compatibility". Right Click the Icon of your program installer/application first, then choose "troubleshoot compatibility". This will allow you to choose on what type operating system your program will run. Just reply back if it still doesn't work.:D rate and vote for me:)) julyallan01_52.jpg

I have aspire 4520 acer laptop.after formatting c drive and installing xp sp-2 ,audio device is missing,kindly advice the solution?


You need to install the support programs for your laptop motherboard. These are also called your "laptop driver software" which is usually shipped or packaged with your laptop. In this CD or DVD Installer, all hardware devices must be well supported by their compatible software drivers.

Now look for the CD/DVD Installer and install the drivers.

Dolby digital


Dolby Digital includes several similar technologies, which include Dolby Digital, Dolby Digital EX, Dolby Digital Live, Dolby Digital Surround EX, Dolby Digital Plus, and Dolby TrueHD.

Dolby Digital, or AC-3, is the common version containing up to six discrete channels of sound. The most elaborate mode in common usage involves five channels for normal-range speakers (20 Hz – 20,000 Hz) (right front, center, left front, right rear and left rear) and one channel (20 Hz – 120 Hz allotted audio) for the subwoofer driven low-frequency effects. Mono and stereo modes are also supported. AC-3 supports audio sample-rates up to 48 kHz. Batman Returns was the first film to use Dolby Digital technology when it premiered in theaters in Summer 1992. The Laserdisc version of Clear and Present Danger featured the first Home theater Dolby Digital mix in 1995.

This codec has several aliases, which are different names for the same codec:

* Dolby Digital (promotional name, not accepted by the ATSC)
* DD (an abbreviation of above, often combined with channel count: DD 5.1)
* Dolby Surround AC-3 Digital (second promotional name, as seen on early film releases and on home audio equipment until about 1995/1996)
* Dolby Stereo Digital (first promotional name, as seen on early releases, also seen on True Lies LaserDisc)
* Dolby SR-Digital (when the recording incorporates a Dolby SR-format recording for compatibility)
* SR-D (an abbreviation of above)
* Audio Coding 3 (relates to the bitstream format of Dolby Digital)
* AC-3 (an abbreviation of above)
* Audio Codec 3, Advanced Codec 3, Acoustic Coder 3 (These are backronyms. However, Adaptive Transform Acoustic Coding 3, or ATRAC3, is a separate format developed by Sony)
* ATSC A/52 (name of the standard, current version is A/52 Rev. B)
