No sound on HP ENVY All-in-One 27b2xx

[DonP1940]

The SOUND display says the unit does not have any audio devices installed. I don't understand this since is is an All-in-One and is supposed to have camera, speakers and mic built in.

@DonP1940 I have a series of steps to help resolve the issue once and for all, and soon this issue with be sleeping with the fishes! You aren't Don Vito Corleone? Are you? 😛 On a lighter note,

That said, there are a few more things I need to know, help me help you:

• Have you attempted to update the BIOS, Video card & Audio drivers to resolve this issue?
  • If not, here's the link to download and install the above updates: Click here

While you respond to that, here's what you need to do:

Step 1: Right-click on the Start button in the taskbar area and then click Device Manager to open the same.

Step 2: In the Device Manager, expand Sound, video and game controllers.

Step 3: You should now see your audio driver name. Most likely you have Realtek High Definition Audio, Right-click on it and then click Uninstall device option.

Step 4: You will now get the following confirmation dialog. Select Delete the driver software for this device checkbox and then Yes button when you see the confirmation dialog to go ahead and uninstall the device driver.

Restart your PC once & it should auto-reinstall a working driver.

Hello. I have followed all of these steps and it has not worked! In particular, in step 3 my audio driver name was not realtek anything, it was Nvidia virtual audio device (wave extensible ) (wdm). I did however go ahead and tell it to uninstall and when I restarted there is absolutely nothing there (including the category for Sound, video and game controllers is also now missing. And, I have no sound (still). Any further instructions??

I assure you I will try my best to get this sorted.

In order that I may provide you with an accurate solution, I will need a few more details and I would appreciate if you could, perhaps elaborate on your concern.

• What is the exact model for your computer?
