Welcome to HP Forums,  

This is a great place to get support, find answers and tips,
Thank you for posting your query, I'll be more than glad to help you out 🙂

I see that you're experiencing difficulties with the volume control on an external keyboard, 
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• Are you using an external HP keyboard?
• Could you please share the screenshot of the keyboard?

While you respond to that, I recommend you to perform the following steps to isolate the issue and arrive at a fix:

1. To mute or restore volume, press Fn+F8. or Fn+F9
2. To decrease volume, press Fn+F10.
3. To increase volume, press Fn+F11. 

Hope this helps! Keep me posted for further assistance.
