The volume is not muted, the cables are correctly plugged in... xmms' equalizer suggests there is sound, but i dont here a thing...
Can someone please help me? I've searched with google, but cant fins any solution, except mysterious links to opensound, alsa, arts, oss, etc...

I finally got an error message, while re-configuring the card:
in dutch:
De kernel module snd-emu10k1 voor geluidsondersteuning kon niet geladen worden. Dit kan veroorzaakt zijn door een foutieve module parameters, een ongeldige IO of verkeerde IRQ parameters

probably in english:
failed to load kernel modules snd-emu10k1. This can be caused by wrong module parameters, a wrong IO or wrong IRQ parameters.
(sorry about the bad translation)

you got the right junk in /etc/modprobe.conf ???
and soundcore enabled in your kernel config ??
