What could cause the onboard sound card to not show in Device Manager after removing a PCI sound card?

It is disabled in the BIOS
The drivers need updating
Not enough power is supplied
USB ports are overloaded

The correct answer is: It is disabled in the BIOS

The scenario of an onboard sound card not appearing in Device Manager after the removal of a PCI sound card can indeed be influenced significantly by the BIOS settings. When a PCI sound card is installed, some BIOS configurations may automatically disable the onboard sound card to prevent conflicts between the two devices. Hence, if the onboard sound card does not show up in Device Manager upon the removal of the PCI sound card, it is likely because the BIOS has not re-enabled the onboard audio option. In many systems, the BIOS settings dictate whether onboard devices are active or inactive. If the sound card is disabled in the BIOS, it won’t appear in Device Manager, regardless of the physical removal of the PCI card. Adjusting the BIOS settings to enable the onboard sound would resolve this issue, allowing the operating system to recognize the sound card once again. In contrast, requirements for updating drivers, power supplies, or USB overloads are less likely to be the fundamental reason for the onboard sound card’s absence in this specific context.
