Laptop Audio Not Working

[Mawy]

Hi,

I hope you're doing well.

A few days ago, my laptop audio stopped working completely. The speakers and headphones don't work. There is a red X on the speaker symbol. When I open device manager, there are two devices that seem not to have drivers "Intel High Definition Audio" and "Intel High Definition DSP". When I try to update the drivers, it says there are no updates available. HP Support Assistant software is detecting that no updates are needed. I've tried downloading sound drivers for my product from HP. They install just fine but the problem persists. When I go, back to Device Manager, the two devices still don't have drivers.  I've tried to go directly to the Intel website. I did a scan on my system and didn't find any sound drivers missing. Instead Intel detected that Intel UHD Graphics 620 Driver needs an update. I downloaded the update but installation failed because "the computer manufacturer doesn't allow driver update for this device as it may affect the functioning of other devices". or something along those lines. 

Please assist because I'm out of ideas on how to fix this issue.

Thanks

Best regards,

Abubakar

Welcome to hp support community.

Run test on the audio device to check for hardware failure

1. Hold the power button for at least five seconds to turn off the computer.

2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.

3. On the HP PC Hardware Diagnostics (UEFI) main menu, click System Tests.

4. Click Extensive Test.

5. Click Run once, or Loop until error. While the test is running, the time remaining and test result for each component are shown on the screen.

If the test passes, uninstall the audio drivers.

• Use shortcut keys Win + X on Windows 10.
• Select Device Manager.
• Expand the entry. Right-click the audio device and select Uninstall device.

Update BIOS, Chipset and audio drivers using HP support community.
