I have a DELL XPS 15Z using my laptop normally suddenly this appeared:
- AUDIO ICON and WIRELESS ICON appeared with a red X
If I put the cursor on the AUDIO ICON it says "no audio output device installed" and I have no sound, the difference is that I do have internet connection.
I´ve done some research on google and in the forums and tried all the options (checking DEVICE MANAGER and RE installing DRIVERS solutions) and the problem remains.
On DEVICE MANAGER under the SOUND CONTROLLERS it appears REALTEK HIGH DEFINITION AUDIO and SONIDO INTEL(R) without any warning.
I read this solution from another post and i'm wondering if it's the only solution:
"Yes! If using System Restore did not solve the problem then restore the laptop to the original factory configuration. Doing this will undo all of your hard work with the laptop since you got it, but if you return it you will lose that work anyway so no net loss. The benefit of doing this is that the audio will work again just like it did when you took the laptop out of the box if a software problem caused the problem. The best thing about doing this is that it is the best diagnostic tool. If the audio does not work after the restoration, then it is because of a hardware failure. Restoration is the gold standard for determining software versus hardware audio problems.
The actual restoration (not to be confused with System Restore) is very quick and easy because the restore image is on the hard drive if you got the computer new from Dell. If it is used then someone might have removed the restoration partition from the hard drive, or the hard drive itself might have been replaced. In that case you would have to do a manual re-installation of Windows from discs and it might be easier to just return the laptop. See instructions for restoration here. It also has instruction for System Restore and other related operations. After restoration test the audio immediately before updating anything. If it is fixed then proceed with caution with updates. The old-school advice about updates is if it ain't broke don't fix it. Mainly this applies to Microsoft. I only let it update security and the OS itself, not drivers.
