Realtek Driver Isssue
Hello everybody,
yesterday after the deployment of Windows 10 Professional (x64) on a new laptot, i found a problem with Realtek HD Audio Controller drivers.
The laptot is an Asus X550LD, and even installing the downloaded drivers from the asus official site the problem persisted (only for the audio while the other drivers have been installed correctly).
In a second moment, trying to figure out the problem, i've distributed with clonezilla a master image created on the same virtual environment of the first Acronis image distributed but the problem did not occur. The only differences between the two images is that are the second image was created with Micrsoft sysprep and acquired with clonezilla, while the first image was create and acquired directly with Acronis Master Image Creator and deployed with Universal restore.
Have you received similar feddback in the past? Have you any suggestions to solve this problem?

Thanks very much. Solution #1 worked for me, as well. The only additional wrinkle was that after the hardware scan found the "new" device, no drivers were available. I then downloaded the audio driver from the manufacturer (Lenovo in my case), installed it, and all is now working fine.

Solution #1 worked!
I have a Toshiba Satellite S55-A5295. Just installed Acronis cloned WD BLUE 3D NAND SSD 1TB and lost audio. Tried several fixes that didn’t work.
Changed Start from 4 to 3 then reinstalled High Definition Audio Controller.
Red X over Sound icon went away - Sound is working now!
Thank you!

There is an easier fix from Device Manager. Open the properties of the Realtek controller. Click Update Driver. Click Browse my Computer. Click Let me choose from available drivers. Highlight the Realtek controller. Click Next. The driver gets corrected.

You can download Realtek audio drivers from Realtek. To get them, you need to go to the website, find the drivers corresponding with the sound card model and your specific flavor of Windows 10 (32 or 64 bit), and download the driver manually. Once you’ve downloaded the correct drivers for your system, double-click on the downloaded file and follow the on-screen instructions to install the driver. If you don’t have the time, patience, or computer skills to update the Realtek driver manually, you can do it automatically with Driver Easy.

@Bobbo_3C0X1, you, Sir, are a genius. I have been trying to fix my audio for days now. I tried downloading and reinstalling the realtek audio drivers, uninstalling the High Definition Audio drivers from the device manager, everything. I finally stumbled across your post above, and the first fix you suggested fixed everything. I can't thank you enough!
