Hi Yvonnelesley,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your sound not playing. Here is a link to perform a hard reset.
I would be happy to assist if needed. How Do I Find My Model Number or Product Number?
Please respond with which Operating System you are running:
Which Windows Operating System am I running?
Have you tried to uninstall your audio driver in device manager?
Please let me know.
Thanks.
