When -M option is given, amixer handles the volumes in percent unit
with the mapping more intuitive to human ears just like in alsamixer.
The -R option is to take the raw value as the volume percentage.
This mode is still used as default.

The man page did not document what happens when multiple ports are
specified; this could be misinterpreted as the events being duplicated
so that they are played on all ports simultaneously. As suggested by
Peter Billam, clarify that these ports are only used for multi-port MIDI
files.

A lot of reports that alsamixer crashes in X terminal when the PulseAudio
CTL plugin is activated were entered to the tracking systems.
I figured that there is a linking clash for the shutdown() function.
The shutdown() function in glibc is socket related, but the alsamixer code
redefines this function and appearently that under some linking
circumstances - which PA client invokes during the runtime dynamic linking
- the wrong function is called.
This patch, for safety, renames the shutdown() function from alsamixer
to app_shutdown(), but it might make sense to figure the real linking
culprit to avoid future surprises.

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

aplay is limited to 32 channels, which makes it impossible to use it for

From the Debian bug report:
"The speaker-test manpage could be improved somewhat by helping a
little bit the user determine how to find out the devices he can test.
Based on http://alsa.opensrc.org/Speaker-test I have make some changes
to the manpage (diff attached) to describe a little bit more how
speaker-test can be used alongside 'aplay'.

The recent addition of pause/resume control via keyboard brought
a problem when aplay/arecord is invoked in background. For avoiding
regressions, it's safer to use non-interactive mode as default and
enable the new feature via an option.

When snd_use_case_get_list (and hence also snd_use_case_card_list) returns
an empty list, alsaucm still attempts to free it. This ends up double-
freeing the returned list, or worse, freeing an invalid pointer, depending
on how snd_use_case_get_list gets implemented. Fix alsaucm to return early
on empty lists to avoid this.

snd_use_case_get_list returns lists of strings that are either:
a) A sequence of single strings
b) A sequence of pairs of strings all flattened into a single list
The current list command assumes layout (b) above, and hence prints
nothing when printing a single-entry list that's actually in layout (a).
Add a new command "list1" to dump lists in layout (a).

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.

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.
