Built-in microphone not detected by the system and/or Windows 11

[Cressi]

Hello.

The microphone was working when the laptop has been purchased but now is no longer working.

By checking the devices, the Stereo Mix is selected as microphone and no other microphones are available in the list except for the one that can be plugged in with a 3.5 mm jack.

On top of the screen there is the camera and the microphone. The camera works but the microphone no. I tried with the app Sound Recorder and the voice is not recorded but only anything is played on the laptop (like a song or video).

I have disabled the Stereo Mix under the "Device Manager", however, if I run the audio troubleshooting with the HP Support

Assistant then the Stereo Mix is restored. I also tried on search for new drivers but nothing.

I have updated Microsoft Windows on the 05/01/2025 but nothing has changed, the built-in microphone is not recognized.

What I can do?

Thank you for your help.

@Cressi, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

Thanks for the detailed information and screenshots. 

Check Hidden Devices

Go to Device Manager > View > Show hidden devices

Expand Audio inputs and outputs

See if "Microphone Array" or "Internal Microphone" appears (grayed or not). If so:

Right-click > Enable

If not installed properly, choose Uninstall, then restart your PC.

Reinstall Audio Drivers Manually

Go to: HP 17 Laptop PC 17-cp2000 (67K42AV) Software and Driver Downloads | HP® Support

Download and install:

Realtek High Definition Audio Driver

Any HP Audio Control driver, if listed

Restart after installation.

BIOS Audio Settings

Reboot and enter BIOS/UEFI (usually by pressing Esc or F10 at startup)

Check if Audio Device is enabled

If there's a toggle for “Internal Microphone” or “Audio DSP,” make sure it's ON.

HP Diagnostics UEFI Test

Restart and tap Esc, then choose F2 for HP UEFI Diagnostics

Run Component Tests > Audio Test and check for microphone test

If it fails or doesn't detect the internal mic, it's likely a hardware or board connection fault.

Create a New User Profile

Sometimes permissions or settings get corrupted:

Create a new local user account

Log into it and check if the microphone is detected under Sound > Recording

Also, refer to this guide: HP PCs - Microphone troubleshooting (Windows 10) | HP® Support

I hope this helps.
