Setting up a new surround sound configuration can be daunting as many speakers need to be placed correctly. Fortunately, Windows 10 includes a small built‑in testing program that can help you set it up. See how you can access it.

First, right‑click the speaker icon on the taskbar and select “Sounds” from the menu that appears.
(You can also open Control Panel and click Hardware and Sound > Sound.)

In the window that appears, select the “Playback” tab, then select the surround sound output device you want to test from the list. On many computers, this will be a device named “Speakers.” Click the “Configure” button to configure your selected device .
(You can also right-click the device in the playback list and select the “Configure [Device Name]”.

A “Speaker Setup” window will open. In the list of audio channels, select the configuration you want to test. For example, if you have 7.1 surround sound connected and want to test it, select “7.1 Surround.”
Then click the “Test” button just below the channel list. You will hear a test beat played through all the speakers in the configuration. As each speaker plays, it will be highlighted in the diagram.
If you want to stop the testing process, click the “Test” button again, which will display the message “Stop”.

If you want to test individual speakers, click on them in the diagram on the right side of the window. When you click on a speaker, a sound will play through that speaker. This can help you figure out if your speakers are placed correctly.

After that, you can press “Cancel” or close the window with the “X” button in the corner. Then, close the “Sound” properties and you’re good to go.
You can also click “Next” and go through the wizard to tell Windows which speakers you don’t have connected, if necessary.
