When phone is on silent or vibrate mode it should also mute the speaker from playing music or multimedia. An app to link the speaker output to the vibrate mode of phone would be great! Silent mode = muted speaker. Uses: When listening to music with your headphones on, and you get a call, the music stops. You unplug your headphones to take the call. When the call ends, the music instantly begins to play again, except this time it comes blasting out of your speakers since your headphones were unplugged! It would be nice to not have to have a separate control. I use a widget to turn my phone on silent mode. So using this same widget to turn the vibrate on and mute speaker would be sweet. I don't think it would be as easy as just muting the multimedia volume because that also controls the headphone volume. So it would have to be speaker output control. Any takers??
