Hello Richard-PA-USA,
Welcome to the HP Forums!
I understand the computer does not produce sound through the speakers. I will do what I can to help you out. To troubleshoot the issue, I would recommend you try the steps in this document: No Sound from the Speakers
This document contains troubleshooting steps such as using the Microsoft Sound Troubleshooter and adjusting necessary settings. I believe trying these steps will resolve the issue. Regardless, please post your results. Thank you for posting on the HP Forums. Have a great day!
