Lost audio after SSD upgrade

First of all, I apologize for posting a message here but there is no option for my Studio 1745 laptop.

I cloned my hard drive to an SSD.  Everything is working after the upgrade except I have lost the audio.

There is an X on the speaker icon and right clicking on it comes up with "No audio devices are installed".

Going to the Device Manager, in Windows 7, shows no "Sound, video, and game controllers"

I'm thinking that the driver may be corrupted. I went to https://www.drivers-dell.com/dell-studio-1745-laptop-audio-driver/

The suggested driver was: Dell Studio 1745 Laptop IDT 92HD73C1 Audio Driver for windows

I downloaded the driver which is R229494.  I ran the .exe file and then the Configuring IDT Audio Driver and Applications window came up.  I then get "The hardware detected is not supported by this IDT software package.  The install will be aborted"

Any suggestions would greatly be appreciated.

Thanks,

Lloyd  Korb
