Hello SJMiller,
Thank you for your reply and apology for the delayed response.
As per the description, I understand that you are trying to test the speakers and subwoofers you discovered that in settings contain only one setup option which contain only two speakers.
I would appreciate if you can provide us the following information to help us understand the issue better.
- What is the make and model of your sound card and computer manufacturer?
- Are you able to hear sound from speakers and subwoofers?
- Have you checked connecting the speakers and subwoofers to any other computer? Do you get the any different result?
As a troubleshooting step, I would recommend you to run Windows inbuilt Hardware and Device Troubleshooter and check if the issue persists.
