Open Device manager (start - control panel - classic view - device manager)
Go down to sound, video, and game controllers
uninstall all audio devices and restart the machine.

I've had the same issue for weeks now. I received the same message about the Sigma tel C-Major audio driver but I couldn't find it anywhere on my computer. I have an HP Pavilion 64 bit notebook and I was finally able to restore my sound by reinstalling the audio codec device. I selected HP Help and Support from the programs menu, then I clicked on Backup & Recovery. I selected Using Backup & Recovery then Using Recovery Manager. After hitting Launch Recovery Manager, click next, the system will ask you if you want to perform a program recovery; select No. Click next and select yes to Would you like to Perform a Driver Recovery? A list will be provided, then select IDT High Definition Audio CODEC Driver. After these steps, the system will begin to reinstall the driver and the computer will automatically restart. When I did this I was able to get my sound back. I don't know how long it wil last but I haven't had any issues so far. Good luck I hope this works for you guys too!
