벨소리 모드가 진동 또는 무음으로 변경되면 미디어 음소거

Normally, when ringer mode is changed to vibrate or silent, media volume remains unchanged. That may lead you to an embarrassing moment if you play a video in office by accident.

Thanks to Awesome Muter, your media volume is always zero when you are in silent/vibrate mode. When normal mode is switched to, media volume may be restored at the value as you wish.

Besides, there is a media volume bar persists on the notification area that lets you know if media volume is mute or not.
