No Audio Devices Found after Win7 Restore

[Albion7]

Hi there.

Win7 Home Premium ACPI x64 based Pc DELL INSPIRON 1545 Service Pack1 SAMSUNG HM500JI driver
Pentium(R) Dual-Core CPU 4.00 GB RAM.

I just restored to an earlier time (Back-up point in 2013 on external hard-drive) due to Win Update issues following installation of Win10 and then reinstalling Win7 a week later. All updates have downloaded successfully.

Now, somehow I have lost my audio. In Device Manager I get following message about my IDT High Definition Audio CODEC:

Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)

The IDT driver is up to date. Audio troubleshooting: No issue detected. Devices and Printers troubleshooting: No problem identified. Audio icon on tool bar has got an ‘x’: ‘No Audio Output Device is installed’.

What is the safest thing to do?

Thank you in advance.

Go to the Dell support/downloads and get the IDT sound driver and reinstall it. If Windows gives you the message about digital signature, ignore it and install the driver.

Access the Dell downloads using your service tag number.
