How to choose the device
- Connect the external sound card (install its driver first if it needs one).
- Open Audio output at the bottom of the main window and choose the sound card’s output device (its name usually includes the brand or model — it depends on your PC).
- Click a sound to test it and make sure you hear it in your headphones and in your streaming software.
