I am not that great at describing this but here goes.  First thing first, alsa 
is part of the kernel.  Specifically, alsa is a set of kernel modules that are 
compiled against a specific kernel tree.  Rpm is a package management system 
that packages precompiled binary object files along with a list of 
dependencies.  If your system does not meet all of the dependencies then rpm 
will not let you install the file.  Apt-get is a program that keeps track of 
repositories of pre packaged binaries (In planet ccrma's case rpm is the 
package management, there are several other systems for linux).  Anyway, what 
happens when you try to upgrade to the newer alsa is apt, through invoking 
rpm, checks the to see that you have the required files on your computer.  If 
you do it downloads them and invokes rpm --install which as I am sure you can 
guess, installs the package.  If you do not meet the dependencies then apt 
tries to see if it can find the required package or packages in its list of 
repositories.  If it can, it will tell you that you need to update various 
packages, if not then, hmmmm I am not really sure what happens then, but I 
assume it tells you that you cannot upgrade.  
>From my perspective there are two options that you can take (that will not be 
more trouble than they are worth).  First and easiest, install the kernel 
version and other files that go with the new alsa.  I would suggest that if 
you go this route do not check upgrade on the packages, check install just in 
case your system does not boot with the new core.  Second and not much harder, 
download and install the src rpm for your kernel, then the source for the alsa 
version you want and follow the directions on the alsa website to compile the 
alsa modules against your kernel version, install the new version remove the 
old and your set.
I hope that helps you out.
