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
http://www.alsa-project.org/main/index.php/Changes_v1.0.17rc2_v1.0.17rc3
And a link to the latest stable release here
