If your PCI sound card stops working, what should you do to use the onboard sound card?

Edit the CMOS settings and enable the onboard sound
Replace the PCI sound card immediately
Uninstall the sound drivers
Update the BIOS

The correct answer is: Edit the CMOS settings and enable the onboard sound

Enabling the onboard sound in the CMOS settings is the appropriate step to take when a PCI sound card is malfunctioning, as it allows the computer to utilize the built-in sound capabilities of the motherboard. When a dedicated sound card is removed or is no longer functioning, the onboard sound chip can be activated to ensure that audio output is still possible. This can typically be done by accessing the BIOS or UEFI firmware during the boot process and changing the settings to enable the onboard sound functionality. Other options may not be effective or necessary in this situation. Replacing the PCI sound card immediately may not be justified if the onboard sound can resolve the issue. Uninstalling sound drivers could lead to further complications, as drivers are essential for both onboard and PCI sound cards to function correctly, and this step does not directly relate to the immediate need for audio output. Updating the BIOS might also be unnecessary unless there are known compatibility issues specific to audio devices, as BIOS updates generally address a range of system improvements and fixes beyond just sound functionality.
