What is usb sound adapter?

A USB sound adapter is a small device that plugs into a USB port on a computer and provides audio output or inputs in the form of headphone jacks, microphone jacks, or both. This type of adapter is particularly useful for laptops or desktop computers that lack a built-in sound card or have a faulty sound card. USB sound adapters vary in quality and price, but many offer features such as 7.1 surround sound output and noise-cancellation technology. They are commonly used for gaming, video conferencing, or listening to music on a computer.
