I have no audio output device installed, my son accidentally deleted my files now i have no audio on my laptop.i downloaded some audio drivers but still none results

Evidently you have uninstalled the driver for your audio system. I would go to Toshiba's support site and look for driver updates for your model and then download the correct free audio driver. Download it, go to that folder and run the setup or install file for it. Here is the URL for their support page:

http://support.toshiba.com/drivers

Enter your model number in the window in the middle of the page.

Good luck.

Go to a Google search web page and type in Sony Vaio NR385E/W optical driver

You should see a list of down loads available

Most common reasons for this trouble are:

• Such kind of troubles arise after some device / software is installed which tries to gain control as default sound device.
• Also while un-installation of certain softwares, some shared files are removed. At times some important shared file can be deleted which causes troubles with working of sound drivers.
• While installing certain games, it tries to gain control of sound or video drivers and may accidentally harm these driver softwares.

Lets see the ways to fix such troubles

Step1 : First of all check what is your default audio device setting. For this, open Control Panel > Sounds and audio devices, open Audio tab as shown in picture below.

See that the Device selected is your sound-card or on-board audio device. It should not be blank or some modem device. Set the Default sound playback and sound recording device correctly from the drop down menu. If your device is not there in this list see the step 2.

Step2: If the step 1 is not successful, it means that your sound device driver software has become either corrupt or has been accidentally un-installed. In such case, install the sound driver from the sound-card/mother-board driver CD. You can also download the latest driver if you don’t have the driver CD. After you install the driver, restart your computer, and then check the settings as in step 1 again

you might have deleted the driver for your internal sound card go to the laptops manufacturers website and see if you can download the driver again, then reinstall it.

you need to go to the acer site and download the correct driver

some file which needed for the operating of that driver might have got corrupted or is not valid ...

once you try uninstalling and reinstalling the driver this will solve your problem ...

if you already did that & still persist the same problem then there may be some file missing in operating system . this might have happened due to some virus attack or while removal of some virus the file which is needed for the operation of that device might have got deleted accidentally ..

so just reinstall the operating system and then try installing the sound driver this will solve your problem ...

if you still persist the same problem then download the driver from net and install this solves your problem (there may be some problem in the driver which you are trying to install may be some file is missing)

so just following these steps your problem will be solved ...
