Windows 7: Problem with driver to IDT high definition audio CODEC

Any suggestions would be appreciated. My audio no longer works. This message appears when troubleshooting:

There is a problem with the driver to IDT high definition audio CODEC. Reinstalling the driver might fix the problem.



The automatic "apply this fix" does not work.

What should I do?

Thanks.

Fill in your system specs. Without it, we have no idea what hardware you own.

Thanks for your patience. I added what I could find to my system specs. Is that the correct information to be helpful?

Yes, that's helpful. Have you visited HP and looked for the correct audio driver for your laptop?

Sorry, but I don't know what you mean my this question. I have searched HP but do not know what to look for. An audio driver does not seem to be listed with the specs.
