[AO OSS] audio_setup: Can't open audio device /dev/dsp: [Solucionado]

Que tal?

De buenas a primeras me quede sin audio para videos en real time (usando un navegador) y para el Smplayer. Amarok sigue funcionando con audio normalmente.

Si me fijo en el log aparece esto:

==========================================================================

Por lo tanto, me fijo en /dev/dsp y NO TENGO ESA CARPETA!! ¡¡??

Si tiro un lsmod me devuelve esto:

A alguien se le ocurre que puede estar pasando??

Gracias a todos!

Si intento con ALSA obtengo esto:

si tenes una instalacion por defecto de debian tendrias que tener alsa ... para comprobar si tenes alguna placa de sonido simplemente usas "alsamixer" en consola ...

podrias mostrarnos la salida de "aptitude search alsa"

saludos ...

Realmente no se que sucedio... hasta ayer funcionaba todo bien.

A ver si me ayudan con esto:

No toque NADA, repito NADA! reinicie la maquina y ahora todo funciona bien. (configurado con ALSA)

alguien me puede explicar cual fue el problema?

algún módulo no cargado jat
