unfortunatly i've tried all of the above.
when i went into the IRC channel i got told exacly what you said about the modprobe thing (i'm still pretty new to using linux and have nfi with that group of files)
i posted in thier forum (http://www.ubuntuforums.org/showthread.php?t=207631
) but the post got 23 views and no replys even after BUMPing it once.
do you know if this card works 100% with linux, or that it's possible for sure?
i have spend a large portion of today trying to make it work, i've manage to make my sound go back to how it was (after borking it trying to activate nvidia drivers)
i hope you can still help.
