I have an older Lenovo T410 laptop on Windows 7 64 bit. Was running fine, no problems, but a game detected that my Nvidia driver was old, and said it needed and update. After downloading the driver directly from Nvidia and installing I have no sound.
DeviceManager shows 4 sound devices
Conexant 20585 SmartAudio HD
4 x NVIDIA High Definition Audio
Service does not has a listing for AudioSrv, AudioEnpointBuilder, or Windows Audio Service.
I don't have a volume icon in the bottom bar.
It appears that the Windows Audio service was deleted but I'm not sure how to get it restored.
SFC /SCANNOW completes and I have rebooted allowing it to restore anything it feels was corrupted.
Any ideas would be greatly appreciated.
