where CRUX keeps ALSA configurations

i am trying to enable ALSA . i have built ALSA support and my sound-card module into the kernel. now as advised by these 2 pages: http://gentoo-wiki.com/HOWTO_ALSA_sound_mixer_aka_dmix http://www.alsa-project.org/alsa-doc/doc-php/template.php?company=VIA&card=VIA+southbridge+AC97+audio.&chip=VIA82C686%2C+VIA8233%2C+VIA8233A%2C+VIA8235%2C+VIA8237&module=via82xx i see that i need to put my configurations (like alias snd-card-0) in a file. now i don't see any "/etc/conf.modules" or "/etc/modules.conf" as advised by ALSA-Project", nor i see any "/etc/modules.d/alsa" file. where does CRUX keeps ALSA configurations ? -- http://arnuld.blogspot.com/
