Sounds like multilib problems I dont have a 64bit box so can't be much help.
run these commands as root:
rpm -qa --queryformat '%{NAME}-%{VERSION}-%{RELEASE}.%{ARCH}\n'|grep alsa

you should see a mix of 64 & 32 bit rpms remove the unwanted with
rpm -e --noscripts --notriggers Your-unwanted-rpm.ix86

watch it the out going rpm could take with it wanted files so I allways
do a rpm -V packagename after. also putting exactarch=1 in yum.conf should 
avoid multilib problems but I cant be certain. if you get stuck post back!
