If you are going to use your restore disks, the system will go back to the factroy settings, which means it will work in a way it worked when you purchased it. So as a result you should surely have your sound card working.
However any software or data which you loaded after purchasing will be lost as well.


Also before using the PC restore, you may also try the system restore.
System restore is a utility using which we can take the system back to a date when it was working fine. It will undo all the changes happened after the chosen date.

Steps for system Restore
Start>Programs>Accessories>System Tools>System Restore.
Than choose a date in the calender when you think that it was working fine.

Any software and programs installed after the chosen date will not be there. You should not loose your data as well.

I hope that i have answered your query.
All the best

SOURCE: Toshiba U300 getting no audio output device

Hello....
No Sound, No Volume Control, Mixer not Found, No Sound device installed…etc etc, This is a generic issue with all Windows OS updates....many of the users are facing this issue....this issue began after an auto update from MS changed many IRQs of Win OS, mainly the Sound and Audio Control system of Windows.
1 - R U facing NO Audio / No Sound issue...?
2 - Is ur Volume Control not responding ?
3 - Is ur Sound and Audio Device in Control Panel Grayed out ?
4 - Do u get a msg "No Active Mixer Devices Installed....when u try to open Volume Ctrl etc etc ?

If ur ans to any one of them is Yes...then u are being spammed by Microsoft....as ur Sound Control IRQ is being frozen by a recent update from Microsoft....
NOTE..THIS…IS…VERY..IMPORTANT...
No file update or any sound driver update can fix it, neither Microsoft is issuing any patch to fix it…or giving any help on this.
Full solution is available in my website (Support page)...it's quite simple process to fix it, and I am not charging any money, just doing FREE service to help everyone affected by this stupidity from Microsoft.
