When I had a different brand of a USB sound card it stopped working on me as well.

Sometimes if you change the default playback device in the Sound properties through Control Panel, or by right-clicking and selecting Playback devices from the volume icon in the system tray.

You can select a different default playback device or switch from speakers to headphones by right-clicking the device and selecting Set as Default Device in the context menu.

Here is a screenshot of the setting I refer to:
