Audio system has gone mute & F6 LED is continuously glowing.

[SAHA100]

audio system has gone mute & F6 LED is continuously glowing. Even after dragging the master volume slider to the higher side ( audio is responding) and releasing it jumps back to zero level and audio is again getting  mute .

From HP SUPPORT SITE I have made all possible attempts (right from updating drivers to online audio diagnostic & checking ,online hardware diagnostic checking etc.) to resolve the issue but failed. The online diagnostic says the "low audio not fixed.

@SAHA100, 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

It sounds like your HP Pavilion x360 is having some software or hardware-related issues with the audio. Since you've already gone through the basic troubleshooting steps on HP's support site, let's try a few more advanced steps to see if we can resolve this.

Check Audio Services

There might be an issue with the audio services in Windows. Let's make sure they’re running.

Press Win + R to open the Run dialog.

Type services.msc and press Enter.

In the Services window, scroll down to Windows Audio and check its status.

If it's not running, right-click it and choose Start.

If it’s already running, right-click and select Restart.

After restarting the service, check if the audio is working.

Uninstall and Reinstall Audio Drivers

Since the audio drivers may be the cause, try uninstalling and reinstalling them manually:

Uninstall Audio Drivers:

Right-click the Start button and choose Device Manager.

Expand the Sound, video, and game controllers section.

Right-click on your audio device (it might be listed as something like "Realtek" or "Conexant") and select Uninstall device.

In the pop-up, check the option Delete the driver software for this device and click Uninstall.

Reinstall Audio Drivers:

Restart your laptop.

Windows should automatically reinstall the audio drivers, but if it doesn’t, go to the HP support page and manually download the latest drivers for your model.

Install the drivers and reboot.

Check Audio Settings in Control Panel

Sometimes, the audio configuration might cause issues. Here's how to reset it:

Open the Control Panel (you can search for it in the Start menu).

Click Hardware and Sound > Sound.

Under the Playback tab, right-click on your audio device (usually "Speakers" or "Realtek") and select Set as Default Device.

If it's already set as default, right-click and choose Test to see if any sound comes out.

Also, make sure Mute isn't selected by mistake.

Run the Audio Troubleshooter

Go to Settings > Update & Security > Troubleshoot.

Click on Playing Audio and follow the on-screen instructions to let Windows detect and fix issues automatically.

BIOS Update

A BIOS update could resolve hardware-related issues that software troubleshooting might not fix:

Go to the HP support page and search for BIOS updates for your model.

Follow the instructions to update the BIOS.

Also, you may refer to this guide: HP Consumer Notebook PCs - Updating the BIOS (Basic Input Output System) (Windows) | HP® Support

I hope this helps.

Please feel free to reply here if you have any questions or if you need further clarification on any of the steps. 

Take care and have a good day.
