It is feasible to use USB external sound card to replace the motherboard's own sound card. The mainboard sound card is damaged, you can install a built-in sound card or use an external sound card. The built-in sound card is mainly used in desktop computers, but there must be a parent PCI slot on the motherboard. The external sound card is mainly used for laptop computers, but also can be used for desktop computers, usually through the USB port access, more convenient to use.
