Andre,

I feel your pain! Im migrating to kernel 2.6.x as well and using an aureal
vortex based card (au8820).. ive gone through numerous attempts at getting
this working, none of which were successful.  Im hoping the aureal portion
of the
alsa driver  will be integrated into the kernel soon so i may once again
hear sound from my linux box!  My only workable option at this point
appears to be turning back to my 2.4.22 kernel setup, which has always
worked fine with an external alsa driver using the au8820 module.  Just
wanted to let you know youre not alone ;)

take care
Jeremy
