No consigo que funcione el sonido.

Jugué con todas las configuraciones en 'Dispositivos de reproducción' y ninguna combinación produjo ningún sonido.

Los dispositivos reales que tengo son un 'Cypress HDMI Audio [Radeon HD 5800 Series] Digital Stereo (HDMI)' que no estoy usando, y un 'Internal Audio Analogue Surround 5.1' que sí quiero usar. También hay una 'QuickCam Pro 9000' conectada a la computadora.
