Hi anilthomas261:
Thank you for your inquiry. I will do my utmost to assist you!
I understand that your audio has ceased to function. I would run the "HP PC Hardware Diagnostics." click here to test for hardware failures. Have you run the "HP Support Assistant" to check for any updates click here? Here is a link to a document on "Sound and Microphone" with links on the page for different issues. click here. Have you done all your windows updates? "How do I Find My Model Number or Product Number" click here. "Downloading or Updating Software and Drivers for HP Computers" click here. If you need more assistance, would you provide the exact model of G61 and the operating system.
