Help! Sound died on my 7805u

So I was playing Assassins Creed today and it crashed. Game was playing fine, sound was working fine. When it crashed, the speaker icon at the bottom had turned into a red x. I clicked it and windows explorer crashed. I then rebooted. Upon rebooting, the red x was back. When I click on it, it runs a troubleshooter that does nothing.

In device manager, the area of "Sound, Video and game controllers" is completely gone. I have searched for hardware changes to no avail, it does not pick up on the sound card. All of the sound options indicate there is no soundcard installed.

I have tried downloading several different conexant drivers and none of them will install because they do not detect the card. I have tried disabling all conexant related drivers from loading to see if it was a driver issue (via Autoruns program), reenabled them, cut and pasted the files manually, powered off, blah blah blah I don't know what else to do.

Any ideas?

 

Bought a Sound Blaster Xfi usb sound card. Problem fixed.

A reformat and reinstall of Windows 7 did not fix the problem.

Two distro of linux did not recognize the card.

OSX didn't recognize a sound card.

Jolicloud didn't recognize a sound card.

So, the 4 year old onboard crap sound burned out today. Whatever. XFi usb with the pigtail cord took approximately 15 seconds to install.

 

That is a new issue. I hadn't seen anyone yet to burn theirs out. Sorry to hear about the issues but good to hear that you have found a fix.........

 

Only one of my internal speakers worked anyway, so it was external speakers or headphones. The Sound Blaster X-Fi Go greatly improved the sound and I simply pig tailed it off a short USB cable to the same stereo cable. It has a headphone input took. Took literally 25 seconds to install and I had sound.

Don't let me forget it was a HUUUUUUUUUUGE upgrade in sound quality. All for $40.
