No Audio Output Device is installed.

I forgot to attached the images. Here it is

Hi Hong,

I'm Benedict, an Independent Advisor. I'm here to help you.

Kindly try updating your audio output driver with Generic device:

1. Open Start Menu.
2. Type Device Manager and Open it.
3. Double-Click on the category "Audio inputs and outputs".
4. Right click on your audio output driver and select "Update Driver".
5. Next select "Browse my computer for drivers"
6. Click on "Let me pick from a list of available drivers on my computer".
7. Make sure the option "Show compatible hardware" is checked.
8. Select Generic device and click Next.

If that doesn't help, try checking your audio output devices in Sounds > Playback, or to do this:

1. Right-click on Speaker icon in the right-side of your taskbar and select Sounds.
2. Click Playback tab and see if speaker device is listed there.
3. If not, right-click and make sure the option "Show Disabled devices" is checked.
4. If the said device is now visible, right-click on it and select Enable.
5. To make it default, right-click on it again and select Set as Default device.

If that doesn't still help, try searching for latest audio controllers/drivers from your PC's manufacturer support website. Download and install them, if any.

If the issue still persist, try to check if the audio controller is disabled in BIOS > Advanced > Onboard/Device Configuration. If so, enable it. And If you need assistance on how to boot your PC into the BIOS please follow these steps:

1. Restart your PC.
2. Once the brand/OEM vendor's logo appears, press the keys Esc, F2, and Del simultaneously until the BIOS display shows up.
3. Look for the audio controller or any related to sound options in the Advanced BIOS settings > Onboard/Device configuration and see if audio controller is disabled. If so, try enabling it, then click the button Exit and Save changes.

Please see if that helps.

Regards,

Benedict P.

Hi Benedict, I finally solve the problem. It's because of the Avast Driver Program that I am using. After several efforts I finally have my audio back. Thank you
