HP Envy 360 Stuck on Mute

[CaitofSpades]

I have an HP x360 2 in 1 laptop. I've been having a problem with my audio off and on for months. The black sound bar that comes up when you change the volume on the computer is permenately stuck on screen with an x at the bottom to indicate it's on mute. The light on the mute key is always on. As a result, the sound doesn't work on my computer. I have tried EVERYTHING to get the mute to turn off to no avail.

Welcome to HP forums. I understand you have audio issues with your laptop.

Don't worry I'll try to help you out.

Did you make any software or hardware changes on your laptop?

Are you able to play audio using a headphone?

Please provide the product number of your PC to assist you better.

As you mentioned the mute button is stuck on your notebook and the light keeps blinking on and off on the mute button.

First, try updating the BIOS and audio drivers on your PC and check if it helps.

Also, update the audio driver using this link:- https://hp.care/2L0jmRG

Please try the steps recommended below.

Go to Control Panel -> Devices Manager -> Audio, Video and Games Controllers

And find there Realtek audio card. Click on it with the right button of your mouse and choose ' Properties '.
Select ' Driver ' tab and select Roll Back Driver check if the issue persists.

Go to Windows Device Manager > Sound, video and game controllers section.
In the list of audio device drivers, look for Conexant High-Definition Audio. 
Right-click and select Disable. The downward arrow displays on this driver, indicating it is disabled. (NOTE: At this point, you won’t be able to play any music files.)
Right-click and select Update Driver Software.
Select Browse my computer for driver software.
Select Let me pick from a list of device drivers on my computer.
You should see a window that says Select the device driver you want to install for this hardware

In the Model box, highlight High Definition Audio Device (this is the substitute audio device driver) and click Next.
At the Update Driver Warning window, click Yes. You should see a confirmation window with High Definition Audio Device displayed. Click Close.
In the list of audio device drivers in the Sound, video and game controllers section, you’ll notice that the High Definition Audio Device now displays instead of Conexant High-Definition Audio.
At the prompt to reboot, click Yes.

If the issue still persists try the steps recommended below.

Is the loudness equalization off? If not, please:
Right, click the speaker icon
select 'Playback Devices'. 
Highlight the default device
Click Properties
Click Enhancements tab
Next to 'Loudness Equalization' take out the check mark in the box.
Click Apply
Click OK

If the issue still persists uninstall the audio driver from device manager and install the drivers using HP recovery manager.

Let me know how it goes.

Cheers.
