This USB fixed my PC's audio that had been gone for 2-3 months. I had an onboard sound card failure and this suffices as a replacement. The company's customer service is great and shipped me out another USB after the first USB was lost in the Royal Mail. The USB's buttons work great but the USB is a little thick so the USB may block other USB ports if parallel to another one. This would work fine on most laptops. I highly recommend it as a cheap audio fix.
