2012 Latitude E6330, Windows 10, Audio IDT 92HD93 issues

The problem isn't with Dell -- it's that IDT got out of the audio chip market, so it never released true Windows 10 drivers.

This isn't a Dell issue - it's an issue with the manufacturer of the audio chip itself.  It's likely possible to get the older drivers working in compatibility mode.

Hello,

Win10 has a native audio driver that should support the audio on the laptop but it doesn't. That is the fault of Microsoft, not Dell.

You should be able to get your audio working by installing the IDT audio driver for Win 7 if you install it using compatibility mode.

First completely remove the IDT driver that is currently installed, if any. Look in the Device Manager under Sound...Controllers. If there is an IDT High Definition Audio Codec, right click on it and select to uninstall. You will be asked if you want to remove the driver software for the device. Check the box (yes). Restart the laptop. Go back to Device Manager and make sure that "IDT High Definition Audio Codec" is gone. If it is there again, keep repeating the process until all instances of IDT High Definition Audio Codec have been removed. If you see "High Definition Audio Device" that is okay -- just ignore it.

Now download and install the IDT audio driver for Win 7.

1. Download and save the audio driver to your desktop or any convenient location on the hard drive.  [There are two "formats" on the driver's page. Scroll down to the 2nd one, named "Hard Drive" format, and download that one, not the 1st one named "Windows Update Package".]
2. Double click on the new folder to extract (unzip) the driver files.
3. The extractor wizard will create a new folder for the driver files. It will be at "c:\dell\drivers\xxxxxx". Write down the exact location that the wizard creates.
4. If the driver begins to install automatically, halt (cancel) the installation.
5. Browse to the driver files on the hard drive (the location you wrote down).
6. Find the "setup.exe" file.
7. Right click on setup.exe to open the context menu.
8. Select the Properties.
9. Select the Compatibility tab.
10. Check the box "run this program in compatibility mode for "... Win7".

If this gets your audio working again, you might  tell your IT department to update their notes regarding installing audio drivers.

am quite disappointed to be frank.

I get where you are coming from, but when you take out the major software in a computer, the operating system, and replace it with a different one, you can expect some hitches. It's like replacing the engine in your car with a different model engine and expecting it to fit together with the original transmission.

Microsoft made a lot of audio changes in 10 that left it incompatible with a lot of computers, then left it up to the computer manufacturers and their vendors to figure out how to fix the Microsoft-created problems. Human nature being what it is, the manufacturers ended up getting all the blame for the problems.
