Computer/Notebook without sound (Audio)? 
So,you've contacted microsoft support team for assistance without any conclution. Due to expensive cost of shipment if, computer is under warranty?You local computer tech has tried his/her best to fix this sound error without any success?
The problem persist after several attempt to restore the sound by most known computer expert (i.e son,daughter's ..ecc)
Now, you are forced to installed a different operating system (i.e linux) but, you prefer windows operating system is windows 7,8.1 ..eccThis problem can be corrected in less than 1 hour.
To correct this error, it requires going to system => registry in order to reset the values which has been modified.

Such modification are cause by automatic chnages by the system itself or due to modification(s) made by incompetent computer tech.
Procedure :
*In order to correct this problem, you'll be requested & instructed on how to take screen shot of the error.
And send the information to me via PM. Such error varies from pc's
*
Upon analyzing this error and possible cause of the issue. I'll prepare specific (the right) valuable's based on the values which has been modified within the registry for your computer tech.Your tech will be required to insert (copy/paste) the exalt values within the system => registry
At this point,the sound should be restored upon restarting your computer.
Note : i also offer remote assistant via skype for correction of such error's.
i suggest computer tech with advance computer knowledge if, you choose to go with this option and they should properly back-up pc before proceeding. Because any error committed within the system => registry might affect proper functioning of your pc.
