MP4 video with AAC audio is handled by the hardware decoders. I'm not positive about this, but there is a chance that the sound doesn't pass through AIR at all.

    There is an audio playback mode you can use to make AIR apps honor the mute switch:

    import flash.media.AudioPlaybackMode;

    SoundMixer.audioPlaybackMode = AudioPlaybackMode.AMBIENT;
