HP Pavilion Gaming Laptop - 16-a0011nw
Microsoft Windows 10 (64-bit)

stereo mix missing on new hp pavilion laptop (Windows 10) problem is not resolved.

I looked at the forum from the link below what the HP Sandytechy20 support user described

I checked one by one
Make Sure Your Microphone is Available for Access = checked
Show Disabled DevicesShow Disabled Devices - doesn't not show

.still problem
and support contact I do not recommend 😞

I scanned for hardware changes - up-to-date and Windows Update up-to-date.
details in my new laptop HP Pavilion:
Realtek High Definition Audio - version 6.0.9018.1 (driver date 01.09.2020 )

Hp support assistan - software and drivers updated.

current Windows update
Version Windows 10 Home
Version 20H2
Build the operating system 19042.870
Capabilities Windows Feature Experience Pack 120.2212.551.0


A bit strange the old Dell Latitude E6440 windows7 laptop is available and working Mix stereo. Why in the new HP laptop Windows 10 stero mix is missing ?
it is not compatible with Realtek Audio (Mix Stereo) driver for HP ?

Please solve the problems in the HP laptop because Mix Stereo is missing.

We reviewed your post and I understand that tried all the troubleshooting. let's reset the  notebook 


Don’t worry, I assure you I will try my best to get this sorted.


I recommend you follow the below steps and check if it helps.


  1. Turn off your HP laptop.
  2. Disconnect all external devices (printers, USB drives, etc.) from your computer.
  3. Remove all recently added internal hardware.
  4. Press the Power button to switch your HP laptop on.
  5. Once your unit starts booting, immediately press the F11 key. Repeatedly press it until you see the Choose an Option screen.
  6. Select Troubleshoot.
  7. Choose Reset this PC.
  8. You can either opt to keep your files or to remove everything.
  9. Select Keep My Files when you want to retain your data. Once you click Reset, your operating system will be reinstalled. The process may take a while.
  10. Choose Remove Everything when you want to remove all your personal files.
  11. You can opt to remove everything solely on the drive where your operating system is installed. On the other hand, you can click All Drives when you do not want to retain any data.
  12. You can also fully clean the drive you selected or just remove your files.
  13. Click Reset.

Hope this helps! Keep me posted.

Hi Praveenbv


I did what you wrote in points 1 to 13 -
repairing pc with "Reset this PC Keep my files" - Windows is refreshed after installation (I haven't updated Windows Update )
I looked at the "Control Panel" in "Sounds" in the "Recording" tab does not show "Mix stereo" from Realtek and the same with show hidden (screenshots img1.jpeg img2.jpeg, img3.jpeg in the attachment)

Please Do you have any other solution to the problem? maybe to install the MIX stereo driver ? or how to install/configure the Mix stereo correctly ?
or maybe Realtek for HP on Windows 10 driver error ? or damaged Windows 10 installation ?
I don't know what to do next after instalation.

I took the steps as you wrote

 Settings -> Privacy section -> App perminission -> Microphone  ( is ON)  screenshot below

Privacy -> microphonePrivacy -> microphone

After restart Windows 10:

run mmsys.cpl in the Recording tab, right-click check the option “Show Disabled Devices“     

no show MIX Stereo 😞   screenshot below:

In RecordingIn Recording


I don't know why you have MIX stereo as you showed in the screenshot and I don't have one.

Can you still solve the problem?

We have done the basic troubleshooting as per the document and the notebook needs to checked taking remote access so that get to know it's a software issue.


I'd suggest you contact HP in your region regarding the service options for your computer or HP Chat Support Team.
