No sound after clean install

There are 4 ways you can download and install audio drivers :

1.From Device Manager

(1).Click Start, type Device Manager in the Start Search box, and then press ENTER.
(2).In the Device Manager dialog box, expand Sound, video, and game controllers.
(3). Right-click the device, and click Scan for hardware changes.
You should see a message that a hardware device is being installed. Additionally, the uninstalled audio device is now present in Device Manager.
(4).Close the Device Manager dialog box, and then determine whether you can hear sound.

2.From the motherboard or installation CD - If your computer came with a motherboard CD, the audio drivers should be on the disk.

3. From manufacturer's website - If you don’t have the CD go to your computer manufactures web page to search for updated sound driver software. Read the instructions on the download pages carefully before installing.

4. Microsoft's Windows Update feature : If there are no updated sound drivers available, use Microsoft's Windows Update feature. Connect to the Internet and try the following items until Windows Update opens:

(1).Click Start, and then click Windows Update (if it is listed).
(2).Click Start, click Settings, and then click Windows Update (if it is listed).
(3).Click Start, click All Programs, and then click Windows Update (if it is listed).
(4).Go to Microsoft's Web site and click Windows Update from the Downloads menu.

from here u can download audio driver...

Go to the toshiba, and download the audio drivers for your laptop.
In the device manager, right click and uninstall the device.
Reboot
Reinstall the audio drivers.
Do it by the downloaded file, rather then the Windows Wizard.
If the downloaded file does not have a setup.exe or an install.exe, go to the device manager, and choose "Update drivers". Point it at the folder you downloaded the drivers to, and let it do the install.

If there is a problem after that, please post any error messages.

First, try pluging in an exteral mic to check the mic itself is not broke. Next Go to the device manager to check for driver problems (control panel, system, Hardware look for yellow ?'s) Check control panel, Sounds and Audio, audio, sound recording, volume. There are just too many ways to mess with the sound settings, and they often seem to just mute themselves!
Good luck

Did you install the file you downloaded? Run it then reboot.

Sound issue can be related to driver, sound settings or hardware itself. If you tell me more about the issue an I will give you step by step solution.
Check if device manager shows the Sound device? When you play a media file does it indicates any error message? Have you unmuted all the channels?
I will look forward your follow post
