Hello rakesh_kaunder.
Thank you for posting on the HP Forums. I understand there is no sound coming from the computer's internal speaker. I apologize for the delay, but I will do my best to assist you!
Before any other troubleshooting is done, I would like to run the Microsoft Fix it utility. This tool will troubleshoot and potential resolve the following:
- Corrupt or disabled audio driver(s).
- Issues with your audio device(s).
- Settings of your audio devices (in case something is not enabled that should be).
Please download and run the utility from this Microsoft website: Automatically diagnose and fix Windows audio playback problems
This utility will potentially resolve the issue on its own. If the issue is not resolved, please try the troubleshooting steps in this HP document: No Sound from the Speakers
I believe all of this troubleshooting will resolve your internal speaker issue. Please post your results, regardless of the outcome. Thank you for posting this issue on the HP Forums. Have a great day!
