Hi Moondancedave,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your HP Pavilion g6 Notebook and no sound on working headphones. Here is a link to troubleshooting audio issues.
I would try restarting the computer with the headphones connected. I would be happy to assist if needed. How Do I Find My Model Number or Product Number?
Please let me know.
Thanks.
