The alsactl Makefile used 'sed $(SED)' which is going to failed when SED
is actually set. Replaced that with '$(SED)', and a few 'sed' calls in
alsaconf Makefile as well. Added AC_PROG_SED to configure to have it
set.

The CD analog playback line is seldom used these days, as all
modern players rip the CD and use the DAC on the sound card.
In addition, it causes background hum on some machines.
Therefore keep it muted by default.

After the previous patch to install udev rules it is impossible to do a
non-root, custom-prefix make install. This is generally not a problem
when building official packages but it can be a pain for developers
and debuggers etc.
This is essentially the same patch as was already made in PulseAudio
in commit e8a5746f2fcae59bfd18d39b621509b3ef130453.

.... 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.

Add minimal systemd and udev support to alsactl so that mixer settings
are restored at boot, when sound cards are plugged in and saved on
shutdown.
This is similar to existing udev/init script solutions in various
distributions.
Note that alsactl is called both synchronously from the udev rules as
well as asynchronously at boot. This is intended, and to ensure two
things:
- At boot the asound.state file might not be readable, since it resides
on a different file system. That means exclusively restoring sound card
settings from udev rules will no suffice, since if the rule is
executed at early boot (for example within udev settle) then the file
will no be readable and cannot be restored.
- We need to ensure that applications monitoring sound cards coming and
going (such as PA) must not get these events before the mixer settings
have been restored. That means the mixer settings must be restored
synchronously withing the udev rules, before the events are passed on
to the apps.
That basically means we need to restore the settings once in udev, to
deal with sound cards becoming available during runtime. And once in
early boot to deal with coldplugged soundcards whose data files might
not have been available at time of plugging. Hence we call alsactl
twice: one from the udev rule, and once from he systemd unit file.

When the range of a control has changed between driver versions, it is a
good idea to restore the same dB value of the control. However,
computing the dB value by interpolating betweem the min/max dB values
duplicates alsa-lib's TLV functions and does not even work for controls
with a linear dB range.
A simple conversion to dB and back can be done if we add the dB value(s)
to the saved state.

By doing this we move them from the .data section to .rodata setion,
or from .data.rel to .data.rel.ro.
The .rodata section is mapped directly from the on-disk file, which is
always a save, while .data.rel.ro is mapped directly when using
prelink, which is a save in a lot of cases.

The initialization procedure consist from default initialization and
state restoration. When restore fails for a reason or the config file
contains inaccurate information, then init is called.
Also, if something fails (init or restore), a file specified using -r
option can be created with description what failed. It can be useful
when user space decides to notify user to set the sound driver properly.

When using alsactl to save or restore the card settings, it currently
skips over controls that don't have the appropriate read/write
permissions. It should also skip over inactive controls, otherwise it
will get an error when it tries to access that control, and will fail to
save the card state (or fully restore it.)
From: Dave Dillow <dave@thedillows.org>
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.
When alsactl saved state has dB level information and an attribute
of a control element is changed after save (e.g. volume range is
changed), try to restore the values to keep the same dB level.
This change requires the new alsa-lib functions for TLV dB
conversion, so we check it in configure (until AM_PATH_ALSA(1.0.16)
works).
Make "alsactl restore" a bit more robust. Now it tries to parse the
compound items in the case that the number of channels was changed.
The former mono-value is expanded to all channels.
adds a space in the help text between "restore" and "<card>" and indents
the rest of the text accordingly to fit.
