Next content shows how I install an external USB sound card adapter onto my laptop and let it be an inside part. My sound card is integrated on the motherboard of the laptop, which has had no sound for almost a week. And this time it breaks completely, even input and output are unavailable, and its microphone has no any function. Even the sound card could not be found in Control Panel. The sound card integration board on the laptop motherboard is burnt; the internal sound card device couldn’t work any more. but I do need this sound card adapter to use the sound device and microphone without changing the motherboard.
