gtk:media-stream-muted (object)

object -- a gtk:media-stream object
setting -- true if the stream should be muted

The accessor for the muted slot gets or sets whether the audio for the stream is muted. Muting a stream will cause no audio to be played, but it does not modify the volume. This means that muting and then unmuting the stream will restore the volume settings.

If the stream has no audio, calling this function will still work but it will not have an audible effect.
