Function Documentation

emotion_object_audio_volume_set()

EMOTION_API void emotion_object_audio_volume_set	(	Evas_Object *	obj,
		double	vol
	)

Set the audio volume.

Parameters

obj	The object where the volume is being set.
vol	The new volume parameter. Range is from 0.0 to 1.0.

Sets the audio volume of the stream being played. This has nothing to do with the system volume. This volume will be multiplied by the system volume. e.g.: if the current volume level is 0.5, and the system volume is 50%, it will be 0.5 * 0.5 = 0.25.

The default value depends on the module used. This value doesn't get changed when another file is loaded.
