toshiba latop speaker not working

Hello sanjay_verma,
Whenever you start having hardware problems the first thing you want to check is your drivers and make sure they are not out of date. To do this open your Device Driver: Right click on My Computer & select properties from the drop down menu. This will bring up your system properties screen.

* Press Hardware Tab at top
* Select Device Manager

You will now see a list and their associated drivers.
if you see a yellow asterisk next to a device or a question mark (depends on your system) that means there is a problem with that driver. try updating your driver. To do this, right click on the device that is showing the problem scroll down to the bottom of the drop down menu and hit update driver.

If you have recently updated your drivers then try rolling back your driver to the previous version.

hope this helps and don't forget the rating.. ^_^
