man.... sorry but i love you!!!
there were 2 months i was searching for making my soundcard work.
now it works and quite well.
the problem was , i think, that all the alsa and emu10k1 driver, except alsa supports, mut be compiled as a module.
no modprobe required.
thanks a lot again!!
works!
edit: ah, to make the sound work I must launch alsaconf every time i start X.
how to skip this little inconvenient ?
