Before you install the device, make sure that your operating system is current (for example, the most recent service pack is installed).
Note: Windows usually saves the files to the Downloads folder that is associated with your user account (for example, C:\Users\your_name\Downloads).
Note: If the Run as Administrator option is not available, you might be trying to run the installer from within the zipped file. Complete the instructions in step 2 to extract the files.
Your computer automatically finishes installing the driver and your device should be ready to use.
The audio format of your source media may be uncompressed (lossless). Uncompressed surround sound audio is not supported by digital (S/PDIF) connections due to bandwidth limitations. When your lossless 5.1 or 7.1 audio content is sent through the Digital S/PDIF connection, data will be lost which can result in limited 2-channel audio playback.
This issue is not an isolated limitation of this StarTech.com audio adapter, as uncompressed surround sound is universally incompatible with digital (S/PDIF) audio.
Digital (S/PDIF) audio supports:
Digital (S/PDIF) audio does NOT support:
Playback of digital surround sound is dependent on a variety of factors, including the audio format of your source media, your playback software, and your audio receiver. Digital (S/PDIF) channel settings are managed by the source and playback devices, and cannot be manually configured like analog audio.
When you troubleshoot issues with a sound card, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:
Stereo audio cables
Speakers or headsets
To test your setup components, try the following:
Use the stereo audio cables, speakers or headsets, and sound card in another setup to see if the problem is with the components or the setup.
Use a different set of stereo audio cables, speakers or headphones, and sound card in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.
When you test your cables, it is recommended that you do the following:
Test each cable individually.
Use short cables when you are testing.
When you test the speakers or headsets and sound card, it is recommended that you do the following:
Press the Windows key + R, type devmgmt.msc, and press Enter to open Device Manager. Check to see if your device is listed under Sound, video and game.
