I remember some issues;
One Try install the latest realtek soundrivers, please google it ok. little busy to search the website now.
they usually solved the problems their
http://www.realtek.com.tw/faqs/faqsView.aspx?Langid=1&PFid=6&Level=3I still can see that it can only be a registry key that is giving you the real trouble in this case.
services.msc stop and start the service check that all audio are started, some systems have HD seperaterly listed
start that too
Unfortunately, I never researched the audio registry keys; I always used realtek drivers...
I agree, lets not re-install Windows, lets just find what registry key is disabled, have you had a search here?
search google; how to disable my sound device, look for websites that refer to the registry "use the term "disable", that is your problem now, if you say "fix", nothing will happen!

http://www.wikihow.com/Disable-Onboard-Soundhttp://kb.esi-audio.com/?goto=KB00040ENhttp://computerstepbystep.com/download.htmlmaybe download this program, see if it is useful tool.
Another website suggests too;
Goto
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\
right click on "MMDevices" select permissions, click add then click advance and then click on "Find Now" then you'll have the list select "Everyone" click OK twice and select Everyone at Groups or usernames box and be sure to select Full Control and Read means both are ticked...
then do this again for this HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render

Has your registry key been deleted?
Does your sound device show up?
Hope you get this; I will test it later myself
