Hoy compré un nuevo auricular para juegos (Gx-Gaming Lychas), y cuando intenté grabar un comentario sobre el juego, noté que siempre hay un ruido de fondo estático, acabo de grabar un ejemplo para que puedan escucharlo (no es necesario descargarlo) ):

Estoy usando Kubuntu 13.04 y la versión Kernel es 3.8.0-19, mi computadora portátil es una Acer Travelmate 5760Z, probé toneladas de configuraciones en Alsamixer y ninguna de ellas dio resultado, realmente necesito que esto funcione así que cualquier tipo de ayuda será muy apreciado

Tuve un problema similar con mucho ruido que variaría con el desplazamiento y otras actividades. Abrí alsamixer y rechacé "Beep", y el ruido desapareció.

Una actualización reciente del paquete pulseaudio incluido con Ubuntu 13.04 (Raring Ringtail) y Kubuntu 13.04 puede estar causando que algunos usuarios experimenten un ruido de fondo persistente o un zumbido. Parece que este error en particular afectará a VLC, Skype y posiblemente a otras aplicaciones que emiten audio. Este problema afecta principalmente a los conjuntos de chips Intel-HDA (audio de alta definición) y los controladores de sonido ALSA en lo que respecta a PA (audio de pulso) "sin fallas".

Es posible que esa estática provenga de su placa base. Intente usar auriculares USB para que no reciba interferencias de la placa base.

Para mí, lo que funcionó fue usar el alsamixer y poner el micrófono con micrófono a 22
