No Audio Device Output is Installed

Hello Oz. Please tell us what operating system is on the laptop.

Hi Jimco!... Windows 10... also fyi: this happened after I upgrade from Windows 7 to 10... Thanks in advance!... Oz

You need to install the Sigmatel audio driver, but there isn't one for Windows 10. So download this Sigmatel driver for Vista and follow these instructions:

1. Download and save the audio driver to your desktop or any convenient location on the hard drive.
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"... Vista".

If installing the Sigmatel driver does not help, you might have to revert the laptop back to an operating system in which the audio did work.

Ok Jim... Thanks for the help!... I will give it a try and keep you posted... Thanks again!... Oz

Jim... sorry to say it did not work... any other suggestion I can try?... Oz

any other suggestion I can try?

Yes, revert the laptop back to an operating system in which the audio did work.

ok... so that would be windows 7... is there a reason that I cannot run windows 10 on this laptop?... I have two exactly same laptops and the other one works great... just curious... oz

Wait, you've got another Latitude D830 with Windows 10?

Jim... When I ran the set up it gives me an error message saying "This is not the correct audio driver for this system... The installer will now exit."

Hi Jim!... Success!... I was downloading the wrong driver... the driver being downloaded was for XP... they do give you a choice for Vista which it works fine... Thanks again for all your help!... Oz

I was downloading the wrong driver... the driver being downloaded was for XP...

Did you use the  link I provided to the Vista driver?
