Instead of a single channel map, multiple channel maps can be provided
in a form of compound (array) to hw and null plugins. In null
get_chmap, the channel map corresponding to the current channels is
copied from the given channel maps.

These cards won't provide the channel maps from the driver itself
because of the dynamic routing. For simplicity, define chmaps in the
configurations, so that chmap querying of individual stereo streams
and combined multi streams works properly.

Some common USB devices are analog only, so prevent the digital
devices from being opened. This simplifies probing the device
in PulseAudio.
I have a "Logitech USB Headset" myself, the "Logitech Web Camera"
was reported by Raymond Yau, and the "Blue Snowball" was reported by
Andy Whitcroft.

When this is done, *.conf files can be placed in that directory and they

A directory (typically /usr/share/alsa/alsa.conf.d/) has been
added into the distribution.

v3: Split file loading into separate function and made error handling
more consistent.

When "default" PCM and control definitions are overwritten by others
like PulseAudio setup, the original system-default defition is lost.
This is a problem when PA is temporarily (or intentionally) disabled
and user wants to use the default dmix.
This patch adds a new standard definition for the system-default,
"sysdefault". This can be used for fallbacks.

After removed the lock, when application using "hw", "front", "rear",

Some broken applications like Audacious don't set any timing parameters.
While the alsa-lib behaviour is to select the smallest period size and

The ice1724-based cards can handle only 32bit while the apps almost
expet 16bit format for SPDIF I/O. This prevents the default config

Note that "plug" isn't used here. Otherwise we get a problem of the

Addeed a new option "truncate" to indicate the behavior of creating
the output file. When it's true (the default), the file is overwritten
and truncated at creation. When false, the plugin tries to open a
unique file with a number suffix.
The global behavior of "file" and "tee" PCMs is defined via
defaults.pcm.file_truncate option. You can overwrite it in ~/.asoundrc.
"./configure" options for selecting ALSA configuration (default
/usr/share/alsa) and plugin (/usr/lib/alsa-lib) directories introduced
by alsa-hg/alsa-lib changeset 2284 cause problems with cross-compilation
and packaging - there is no way to redefine them in runtime, during
installation phase.
This patch adds a level of indirection between constants and their
usage - alsaconfigdir for ALSA_CONFIG_DIR and alsaplugindir for
ALSA_PLUGIN_DIR - which can be redefined during "make install" stage.

The direct plugins have the automatic format-detection feature but it
wasn't enabled properly in the interface. Now you can pass the format
"unchanged" to make the plugin detect a proper format.
This will change the default format of some drivers, such as, HD-audio.
