How to turn off the onboard audio

[IlyaMak]

Hello,

I bought new audio card C-media 8738 Lx for the PCI E slot but the computer doesn't see it at all. It seems to me that PCI-E slot is not working. In device manager of Windows I see only two audio devices: 1) ATI Radeon HDMI from the video card and 2) on board Realtek ALC662.

The first question : Is it possible to install this audio card on my computer that it will work?

The second question: In the Internet I saw the advice to turn off the onboard audio card in Bios. But in Bios i cant find the suitable setting to do so. The version of bios is: Hewlett-Packard 786G7 v01.02.

Greetings,

Welcome to the forum.

I am not a HP employee.

You should be able to disable onboard audio in the BIOS.

First, install the new audio card in the MB . Onboard audio cannot be disabled unless a discrete audio card is installed in the MB.

Boot to the BIOS. (F10).

Go to the Security Menu.

Select Device Security.

Disable System Audio.

Check Slot Security to ensure all PCIe slots are enabled.

Save and Exit the BIOS.

Install the driver for the new audio device.

The new audio device should now be visible in Windows Device Manager.

Regards
