Esto funciona en la mayor\u00eda de los casos, pero los problemas siempre est\u00e1n en los detalles. \"M\u00d3DULO\" se define cuando el c\u00f3digo objetivo (es decir, el n\u00facleo de sonido) se construye como un m\u00f3dulo; pero esto no significa que la persona que llama tambi\u00e9n est\u00e9 integrada o no. Es decir, cuando solo el n\u00facleo de sonido est\u00e1 integrado (CONFIG_SND=y) mientras el controlador es un m\u00f3dulo (CONFIG_SND_USB_AUDIO=m), el puntero del m\u00f3dulo pasado se ignora incluso si no es NULL, y tarjeta->m\u00f3dulo permanece como NULL.
