<interface name="ext_audio_surface_manager_v1" version="1">
<description summary="indicate surfaces playing audio">
This interface allows clients to inform the compositor which of their
surfaces are playing audio. The compositor can use this information to
show corresponding indicators in its UI.
Warning! The protocol described in this file is currently in the testing
phase. Backward compatible changes may be added together with the
corresponding interface version bump. Backward incompatible changes can
only be done by creating a new major version of the extension.

<interface name="ext_audio_surface_v1" version="1">
<description summary="surface extension object to control the audio state">
This interface allows the client to inform the compositor when a surface
is playing audio.
Each surface is in one of two possible states: started or stopped. By
default, each surface is in the stopped state, indicating that it is not
playing audio. The client must make the started request to transition to
the started state.
If the surface is destroyed before this object, this object becomes inert.
</description>
<request name="destroy" type="destructor">
<description summary="destroy the extension object">
Remove the extension object from the wl_surface.
The surface is automatically reverted to the stopped state. If the
client wants to synchronize this with a wl_surface.commit, it should
make a stopped request and commit the surface before destroying this
object.
</description>
</request>
<request name="started">
<description summary="the surface has started playing audio">
Transition the surface to the started state, indicating that it has
started playing audio.
It is not an error to make this request when the surface is already in
the started state.
The audio state is double-buffered, see wl_surface.commit for details.
</description>
</request>
<request name="stopped">
<description summary="the surface has stopped playing audio">
Transition the surface to the stopped state, indicating that it has
stopped playing audio.
It is not an error to make this request when the surface is already in
the stopped state.
The audio state is double-buffered, see wl_surface.commit for details.
