Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, to provide an accurate resolution, I need a few more details:

• Did you make any changes to the settings of your PC prior to the issue?
• When was the last time it worked fine?
• What are the troubleshooting steps you have tried so far?
• Have you checked the audio via headphones or external speakers?

While you respond to that, let's try these steps: 

Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8. (Refer to the removable and sealed battery)
BIOS default:(do not skip any troubleshooting steps, even if you feel steps are repeating)

1. Turn off the computer and wait five seconds.
2. Press the Power button to start the computer, and repeatedly press the F10 key to enter the BIOS setup menu.
3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and    Exit.
5. Use the arrow keys to select Yes, then press Enter when asked to Exit Saving Changes?
6. Follow the prompts to restart your computer. 

Hope this helps! Keep me posted for further assistance.

When i purchased the PC everything was working fine, as more and more windows updates came to my system I noticed the right channel stopped working. This problem started when I was still running on windows 10. The audio is working perfectly via headphones, but the right channel of the external speakers is not working. The last time it worked fine was at the point of purchase. I've tried so many troubleshooting but problem still persists

Thank you for posting back. 

I appreciate your efforts to try and resolve the issue.
The last thing I can suggest, try and restore the OS back to the factory default, which will isolate whether it’s a software or hardware issue.  The HP Cloud Recovery Tool allows you to download recovery software to a USB drive. You can use the downloaded recovery image file in order to install the Windows operating system.
