Good queston.  I know because of the package.  You can find the driver 
version by running    cat  /proc/asound/version    and the utilities 
version by running   aplay --version   .
I couldn't find a way to get the library version.  You can use the run 
   alsa-info.sh --no-upload     and the output will have the driver, 
library, and tool version at the top.
The script is found at http://www.alsa-project.org/alsa-info.sh

libasound is always version 2.0.0, no matter the alsa-lib version.  I 
presume that is to facilitate testing and upgrading.  Nothing will break 
with newer versions.  So that is unrelated to alsa version.

You can find the latest beta versions of all the alsa source here
