How can I get the installed ALSA version?
To find out the version of alsa you are using, just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:
cat /proc/asound/version
The version of the kernel drivers is shown in /proc/asound/version, but this depends only on your kernel version (and the latest version shows nothing but the kernel version number).
To get the version number of the user-space tools, execute aplay --version.
