It may be useful to collect the basic sound card information.
The output is in the YAML structured syntax (human and machine readable).

The /var/lib/alsa/card<NUMBER>.conf.d directories should be emptied
when the card is initialized. Implement this functionality directly
to alsactl.

It is handy to remove all card controls created by applications.
This change allows to remove those controls for all cards, selected
card or selected card with a control id filter list like:
alsactl clean 0 "name='PCM'" "name='Mic Phantom'"

The state management can run at low priority, add --nice and --sched-idle

For the plug-and-play hardware, like USB devices, it may be helpful
to manage the sound state periodically, before the devices are removed.
This change implements new commands 'daemon' and 'rdaemon' to save
the sound state in defined intervals when the sound controls are changed.
The udev rules can notify the daemon using the 'kill' or 'nrestore'
commands to rescan available cards in the system.

.... and add configure switch for it.
/etc might be on a read-only partition which is not suitable for dynamic
data such as the mixer settings. Hence move the location of asound.state
to /var/lib.
This is based on a patch from Ubuntu/Debian which hardcoded the pah in
/var/lib.

Set -F option as default for restore. There are still too many systems
that are too lazy to set -F option...
Added the new -P option to back to the old behavior.
This patch converts hyphens to minus signs in the man pages (for options,
emails, or command line examples).
This patch also closes one font modifier in iecset.1.
