If the audio files stored on a USB device are not functioning properly, you need to fix the codecs currently installed on the computer. Thankfully, these codecs are available online so it only takes few minutes to fix the USB audio codec driver problem.

  1. 1

    Open your Internet browser and navigate to the Microsoft codec download page (see link in Resources).

  2. 2

    Select the "Download" link next to the audio file you are attempting to play. Momentarily, the file begins to download directly to your computer.

  3. 3

    Double-click the downloaded audio codec file. In a moment the installation wizard appears on your screen. Oftentimes these codec files are paired with video file codecs. You are unable to split the different codecs apart, so the video information is going to install onto your computer also.

  4. 4

    Choose "Next," then leave the remainder of the prompts as-is until you reach the install page. Click "Install" and the drivers update and install onto the computer. Now when you attempt to use a USB device the audio codec is used to properly play the file.
