Hello Tan_a,
Welcome to the HP Forums! I hope you enjoy your experience!
I understand the computer has lost its audio abilities. I will do what I can to assist you!
Since it has occurred recently, I would suggest performing a System Restore. You can restore the computer to a point in time (restore point) before the issue first occurred. For more information on how to do this, please reference this Microsoft website: System Restore
Before I provide any other information, I would like to know if this works. If it does not work, please provide the operating system of the computer. If you require assistance locating this information, please reference this website to determine your Windows operating system.
Thanks for bringing this issue to the HP Forums. Have a great day!
Mario
