A bash completion script for a selection of tools from the alsa-utils repository of the ALSA project (https://github.com/alsa-project/alsa-utils).
Includes a trivial executable alsa-list-ctls that lists the mixer devices (ctl devices in the ALSA config) as there appears to be no equivalent to aplay -L for listing CTLs.
