Thank you for posting on the HP Support Community.

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

• Have you tried with external speakers or earphone?
• Is there any exclamation mark or red X on the speaker Icon?
• Does device available in device manager?

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

1. Turn off the computer, and then connect the power cord.

2. Press and hold the Windows key and the B key at the same time, and then press and hold the Power button for 2 to 3 seconds.

   

3. Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.

Hope this helps! Keep me posted for further assistance.
