Hi! , Welcome to HP forums.
I understand after the latest windows update the audio on the PC has stopped functioning.
Don't worry I'll try to help you out.
Did you make any software or hardware changes on your PC?
Have you tried checking with headphones does the issue persist?
Please share the product number of your PC to assist you better.
Excellent description and a great diagnosis done. It is greatly appreciated.
Try the steps recommended below.
Go to Windows Device Manager > Sound, video and game controllers section.
In the list of audio device drivers, look for Realtek or IDT High-Definition Audio. This is the device driver for BeatsAudio (a little bit sneaky, wouldn’t you say?).
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. NOTE: If you see a window that says something like This is the best driver for this device, exit the window and repeat steps 4, 5, and 6.
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 Realtek or IDT High-Definition Audio.
At the prompt to reboot, click Yes.
If the issue still persists try the steps recommended below.
background intelligent transfer service (BITS) transfers files (downloads or uploads) between a client and server and provides progress information related to the transfers. If the BITS service is turned off, windows update may have problems delivering files to your computer.
Start the BITS service click start, and then click run.
Type services.msc in the open box and then click ok.
Right-click background intelligent transfer service, and then click properties.
On the general tab in the startup type box, click Automatic, and then click apply.
In the service status section of the properties dialog box, verify that the BITS service is started. if it is not started, click start.
Click apply, and then click ok.
Restart the computer.
Make sure your audio device is set as default
1) Right click the volume icon at the bottom right corner, and click Playback devices.
2) Check your audio device in the Playback tab. Make sure there’s a green check next to your audio device, and that shows that your audio device is the default playback device.
3) If your audio device is not the default device, click Set Default. Then click OK to save.
3) Test the sound on your laptop so see whether there is any sound.
Also, uninstall the audio drivers from the device manager and install the latest audio driver on your PC using HP support assistant.
Refer this article to know more information about using HP support assistant.
If the issue still persists try running a system diagnostics test from your PC and check if the hardware components on your PC are functioning correctly.

Let me know if this works!
Have a great day! :)
