list->card is wrongly assumed to be initialized, but the previous
initialization is within a conditional that is false when only
card-independent devices are found. (This is the case when searching
for mixers on my system; the end result is that the "pulse" mixer is
listed three times.)

snd_device_name_hint() corrupts the config name space after its call.
This results in the error from the suceeding calls of snd_pcm_open()
after snd_device_name_hint().
The bug is in try_config() in namehint.c; it calls snd_config_delete(res)
but res can be two different objects in the function. One is the object
obtained via snd_config_search_definition(), and another is the one from
snd_config_search_alias_hooks(). The former is the expanded objects,
thus it should be freed. But, the latter is a reference, and must not be
freed.
This patch adds the check to free or not.

and appl_ptr, but also by 'runtime->delay' property,
either SNDRV_PCM_IOCTL_DELAY or SNDRV_PCM_IOCTL_STATUS ioctl

Previously 'runtime->delay' was ignored in case 'hw->sync_ptr'

In snd_pcm_hw_params_choose(), set the buffer size before the period
size and time as default. This will give more useful configuration for
most of apps, i.e. larger buffer size.
For apps that require the old behavior, now the function checks the
environment variable $LIBASOUND_COMPAT. If this variable is set to
non-empty, the hw_params is determined in the old way, first period
then buffer sizes.

In the normal mmap mode, the stream isn't started automatically even after
the data >= start_threshold has been written. However, in the
mmap-emulation mode, the stream is started because it uses
snd_pcm_write_areas() internally.
As a workaround for this inconsistency, start_threshold value is changed
dynamically in sw_parmams and mmap_commit callbacks in mmap-emul plugin.
Meanwhile, start_threshold for slave PCM is set to boundary so that only
this plugin (or the one over it) can control the start of the stream.
This will fix problems in some apps using pulse plugin in the mmap mode.

Summary: load_for_all_cards fails with existing configuration elements
In snd_config_hook_load_for_all_cards, the first call to
snd_config_search attempts to locate an existing configuration node with
the name of the driver. Typically none is found, and everything is
good. However, if such a node is located, the next line assumes it is a
leaf node with type 'string' and calls snd_config_get_string to fetch
the string value. If this fails, the entire hook is abandoned.
Because of this, setting something like the following in asoundrc:
cards.<driver name>.foo 0
is sufficient to disable the entire card-specific configuration.
As a concrete example, I have a HDA-Intel sound card. dmix.conf includes
a way to set period_size, period_time, and periods by using
configuration elements of the form cards.<driver name>.pcm.dmix.<var>.
In ~/.asoundrc I add
cards.HDA-Intel.pcm.dmix.period_size 1024
This will cause HDA-Intel.conf to fail to load, and the pcm defined in
default.conf will fail to find the device-specific pcm
cards.HDA-Intel.pcm.default, and fall back on the default pcm using
plughw. By attempting to configure dmix, I have disabled it.
