problema con mplayer

tengo un Debian 3 con un kernel 2.4.24 y estoy en unstable. El problema es el siguiente: instale el mplayer, pero cuando hago "mplayer <archivo>" me aparece lo siguiente:

como se puede ver tengo chip nvidia, cuando hago mplayer <archivodevideo> me reproduce el video pero sin sonido. Otra cosa: a pesar de aparentemente no reconocerme la placa de video, los archivos de sonido los puedo reproducir, ese mismo archivo que intento reproducir con el mplayer, cuando navegando por los directorios le hago "click" me ejecuta un reproductor y lo reproduce bien, los sonidos del sistema se escuchan

Me baje el tar.gz de la pagina de nvidia, el modulo del sonido se llama "nvaudio.o", compilo las fuentes del driver, hago un modconf y efectivamente en la parte de drivers de audio aparece nvaudio.o, cuando intento cargarlo me aparece esto:

Installing module nvaudio. If the device isn't there, or isn't configured correctly, this could cause your system to pause for up to a minute.

/lib/modules/2.4.24/kernel/drivers/sound/nvaudio.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg

Bueno, espero que alguien me pueda dar una mano
