@Rhydian,

Welcome to the HP Forums 🙂 I would like to take a moment and thank you for using this forum, it is a great place to find answers. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for First Time Here? Learn How to Post and More. I see from your post that you are having issues related to audio on your HP notebook. Don't worry I'll be glad to help you with this.

To provide you with an accurate solution, I'll need a few more details:

Have you recently made any software or hardware changes on the PC before the issue started?

Have you tried to update the drivers either using Windows update or using HP Support Assistant?

Did you try to run a test on the Audio from F2?

Perform a Hard reset on the notebook: 

Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a "Hard Reset". Use the following steps to perform a hard reset on a computer:

1. If Windows is open, click Start and then Shutdown.

If Windows is not open and the computer has power, press and hold the power button on the computer until the computer shuts off.

2. With the power off, disconnect the power cord from the back of the computer.

3. With the power off and the power cord disconnected, press the power button on the computer for 5 seconds. The power light indicator on or near the power button might turn on briefly but then go out.

4. Reconnect the power cord and turn on the power.

Next thing, I would suggest here is to Run Windows Updates troubleshooter -

Download and install the troubleshooter from this link.

Now try to perform Windows Updates - 

1) In the search box, type and open Windows Updates. 
2) Check for updates. 
3) If the updates are available, click on install and restart the computer. 

Step 1 Run Audio troubleshooter -

1) In Windows, type "Find and fix audio" into Search, or right-click the speaker icon on the taskbar and select Troubleshoot sound problems.
2) Select Find and fix audio playback problems or Find and fix audio recording problems from the Search results.

If the issue persists, I would suggest here is to uninstall the audio drivers from device manager: 

Let's start off by uninstalling the audio drivers from device manager: 

Right-Click on start button> click device manager> expand sound video and game controllers>then select the sound drivers and right-click on it and uninstall the audio drivers.

Then check the box delete the software for this device.

Restart the computer and then update the Bios, Chipset and audio drivers on your PC from our HP support website, using this link.

Also, download and install HP support assistant on your PC. It should automatically download and install the latest updates and drivers for your PC.

Refer this link to know how to use HP support assistant.

Once done, restart the computer.

Please let me know if this resolves the issue, or if you require further assistance!

Eagerly waiting for your response!
