How can I see what ALSA version is installed on my machine?

I tried:

$ alsa --version
Usage: /sbin/alsa {unload|reload|force-unload|force-reload|suspend|resume}

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.

  • aplay is part of the alsa-utils package. But the other user-space packages are typically updated in parallel. – CL. Dec 27 '15 at 20:53
