Не работает звук

система debian 5 (stable), только что поставил, из коробки не заработал звук

при запуске sudo alsaconf

появляется ошибка
Loading driver...
Setting default volumes...
amixer: Mixer attach default error: No such file or directory

у гентушников подсмотрел что нужно загрузить модули
# insmod snd-mixer-oss
# insmod snd-pcm-oss

на что у меня вылетают опять ошибки
