Windows USB Drivers

If you have Windows, we have drivers.

If you're going to use a Windows PC with Bifrost or Gungnir via USB, you'll need to install our drivers. These drivers work with Windows 8, 7, Vista, and XP systems, though best performance is on Windows 7 and 8 machines.

You do not need drivers for Mac or Linux.


Download the package here for Windows 8, 7, and XP:  Schiit Unified USB Drivers 1.03 (14MB)–>

Download the Windows Vista package here: Schiit Vista Drivers 1.03 (7MB)-->


Once you’ve downloaded the drivers:

Step 1: Go to your Downloads folder (or Desktop, or wherever you had Windows put the drivers.)

Step 2: Double-Click on the Schiit_USB_1.03.zip archive to expand it.

Step 3: Click on the folder: Schiit_USB_1.03 to open it.

Step 4: Connect Bifrost or Gungnir with a standard USB cable, 2M or less in length, with true USB 2.0 rating.

Step 5: Double-click on “setup.exe.” This will automatically select the correct driver for your version of Windows.

Step 6: Follow the prompts from the installation program to install the drivers. You may have to restart your computer.

Step 7: In your Control Panel/Audio Devices, select “Speakers: Schiit USB Interface.” You may also have to select it in the player software you are using in order to get output.

Step 8: Enjoy your music!


Note: On some Windows systems, the driver download will show up as "Encrypted," and will not install. In that case, follow this procedure: 

a. After unzipping the drivers, you'll have a directory called CM6631_6631A_-1.03(CR).

b. Right-clicking on the directory gives a menu with a "Properties" button on the bottom.

c. Click on Properties, On the first tab, "General," click on the "Advanced" button under "Attributes." You will see four checkboxes, the last of which is "Encrypt contents to secure data."  

d. Uncheck that box and click "Apply." Unencrypt for all subdirectories, and proceed with Setup as in Step 5.
