No, do *not* remove alsa-lib or alsa-utils (they are core CentOS packages).

Have you rebooted since installing kmod-alsa as the kernel will need to 
load the new drivers? If not, please reboot and retest.

If it's still not working after updating ALSA using kmod-alsa from 
elrepo (after a reboot), then you might want to consider removing that 
package as it hasn't fixed the problem in your case:

yum erase kmod-alsa

Hope that helps.
