have you used the alsa driver from alsa-project.org or from the kernel source?
and what kernel version do you have?
if you have a 2.6 kernel
when you run 'make menuconfig' try to select Open Sound System instead Advanced Linux Sound Architecture
in
Device Drivers -->Sound
this is a solution ...
an other solution is to try to pass the correct parameters to the module
this is only a personal comment : I think it's not the bettere solution using the YAST to configure the sound card ..
