Hi,
am tyson
i red ur compliant
the best solution i can say that u have to restore the data
for that follow this:
click on start->programs->Accessories->System Tools
in that u will see a program called "system restore"
click on that and it will run.
in that find any date before u lost ur sound and click on date which is before the problem then click restore.
i think it will word.
if it didn`t work
follow this:
put ur laptop driver cd on the cd/dvd drive
in the desktop right click on the "my computer" icon click "properties"
a menu will appear in that click on the "hardware" tab
in that click on the "device manager"
on that click on the plus(+) symbol of "sound,video and game controllers"
on that right click on "legacy audio driver" click on "properties"
a window will appear in that click on the "driver"
on that click on "upgrade diver" then select your cd driver in that and click next
it search for ur driver in cd if ur lucky u will get back ur sound.
if u read this and get solved the problem please mail me
