caching of sounds in the sound server. One of "permanent",

frequently used sound events such as those used for input
feedback. "volatile" may be used for cacheing sounds in the sound
server temporarily. They will expire after some time or on cache
pressure. Finally, "never" may be used for sounds that should never
be cached, because they are only generated very seldomly or even
only once at most (such as desktop login sounds).

or gsound_context_play_full() it will default to "never". If it is not

is:

* Initialize the #GSoundContext
* [Optional] Set any global attributes using gsound_context_set_attributes()
* [Optional] Cache any frequently-used sounds (for example, sound
  effects for a game) using gsound_context_cache()
* Play sounds using gsound_context_play_simple() or gsound_context_play_full()
* Close the connection to the sound server and clean up the context using
  g_object_unref()

#GSoundContext implements the #GInitable interface, so if created with
g_object_new() (as typically happens with language bindings) then you must
call the g_initable_init() method before attempting to use it.

# Simple Examples

In C:

|[&lt;!-- language="C" --&gt;
GSoundContext *ctx = NULL;
GCancellable *cancellable = g_cancellable_new();
GError *error = NULL;

ctx = gsound_context_new(cancellable, &amp;error);
if (error) {
    // handle error
}

gsound_context_play_simple(ctx, cancellable, &amp;error,
                           GSOUND_ATTR_EVENT_ID, "phone-incoming-call",
                           // other attributes...
                           NULL);

or, using Python via GObject Introspection:

|[&lt;!-- language="Python" --&gt;
from gi.repository import GSound

ctx = GSound.Context()

try:
    ctx.init();
    ctx.play_simple({ GSound.ATTR_EVENT_ID : "phone-incoming-call" })
except:
    # Handle error
    pass
]|

or using Vala:

|[&lt;!-- language="Vala" --&gt;
try {
    var ctx = new GSound.Context();
    ctx.play_simple(null, GSound.Attribute.EVENT_ID, "phone-incoming-call");
} catch (Error e) {
    // handle error
}
]|

# `play_simple()` versus `play_full()`

The above examples use the gsound_context_play_simple() method for
playing sounds. This is a "fire and forget" method which returns
immediately and does not block your program, and is suitable for most use
cases.

If you need to find out when the sound finished (for example to repeat the
sound) then you can use the gsound_context_play_full() version. This
is an asynchronous method using the standard GIO async pattern, which will
run the supplied #GAsyncReadyCallback when the sound server has finished.
It is guaranteed that the callback will be run exactly once.

Note that calling gsound_context_play_full() with a %NULL callback is not
equivalent to calling gsound_context_play_simple(). When calling
play_simple(), errors which occur before the sound is passed to the sound
server are reported immediately, whereas with `play_full()` these are reported
in the callback. If you pass a %NULL callback to gsound_context_play_full()
you will not be able to receive these errors, so it is strongly recommended
to avoid doing this and use gsound_context_play_simple() in the case when
you don't need to be notified when the sound has finished.

# Passing Attributes

GSound supplies information to the sound server by means of attributes.
Attributes can be set on the #GSoundContext itself using
gsound_context_set_attributes(), or supplied in a `play()` call. Attributes
set on the context will automatically applied to any subsequent `play()`
calls, unless overridden by that call.

In C and Vala, attributes are passed as %NULL-terminated list of
(attribute, value) pairs. When using GObject introspection, attributes are
typically passed using a language-specific associated array, for example
a dict in Python or an object in JavaScript.

For the list of attributes supported by GSound, see
[GSound Attributes][gsound-GSound-Attributes].

# Caching # {#caching}

If supported by the sound server, frequently-used sounds may be cached. This
may be useful, for example, for sound effects in a game. To cache a sound,
either call gsound_context_cache(), or pass the special
#GSOUND_ATTR_CANBERRA_CACHE_CONTROL attribute to one of the `play()`
functions.

For example, in the startup code for a game you might include something
like the following (error checking omitted):

|[ &lt;-- language="C" --&gt;
GSoundContext *ctx = gsound_context_new (NULL, NULL);
gsound_context_cache(ctx, NULL,
                     GSOUND_ATTR_MEDIA_FILENAME,
                     "/path/to/player-spaceship-fire-laser.ogg",
                     NULL);
]|

There are three caching modes available, "permanent", "volatile" and "never".
The default mode when calling gsound_context_cache() is "permanent", and
the default mode for gsound_context_play_simple() and `play_full()` is
"never".

See the documentation for #GSOUND_ATTR_CANBERRA_CACHE_CONTROL for more
details.</doc>
