Thank you for posting on HP Support Community.
 

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

Run the audio troubleshooting tool in Windows to automatically fix common audio recording and audio playback problems with your computer.

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.

3. Click Next.

4. Select the device you want to troubleshoot, and then click Next.

5. Wait while the troubleshooter detects problems and makes changes (or prompts you to make changes).

   

6. When the troubleshooter is done, the Troubleshooting has completed page displays, listing any problems found and what changes were made to the computer.

   NOTE: For detailed information about the troubleshooting, click View detailed information in the troubleshooter window.

   

7. Click Close.

8. If a recommended action displays, select Apply this fix or Skip this step to continue to search for other problems.

Test for sound.
 

Hope this helps! Keep me posted for further assistance.
