So you have the frustrating problem of “Audio not configured” messages and no sound even though you know you have audio devices connected to your PC. The problem may be in your BIOS settings.
If you have the “X” symbol over the speaker icon on the system tray (not the circle with the line through it that shows when audio is on mute) and your audio refuses to work, even after re-installing the audio drivers and checking the connections to your devices, your audio may be disabled.
There are 2 main BIOS settings that can disable your computer’s audio capability. Your BIOS may vary, this example works on many different HP computers.
Here’s how to fix your PC audio problem in the BIOS:
1) Using the F10 or ESC key to get into your BIOS setup, tab with the arrow keys to Advanced –> Device Options –> Internal Speaker. You may see it listed as “Disabled”, tab to enabled and apply the setting. (again your particular BIOS settings may vary)
2) While remaining in the BIOS setup, arrow over to Security –> Device Security –> System Audio. The audio device may be listed as “Device Hidden” If so, change the setting to “Device Available”.
Some BIOS versions give the ability to disable or enable individual audio jacks such as the front and back jacks found on a PC tower.
