Programatically disable ALL sound and vibration in android

Question

I want to disable ALL sound and vibration from the android device. As per the answers to similar questions, I'm currently using the following code to mute all the audio streams, set the ringer mode to silent, and to fake a voice call scenario:

AudioManager amanager=(AudioManager)getSystemService(Context.AUDIO_SERVICE);
    //DOESNT DISABLE ALARM CLOCK
    amanager.setStreamMute(AudioManager.STREAM_NOTIFICATION, true);
    amanager.setStreamMute(AudioManager.STREAM_ALARM, true);
    amanager.setStreamMute(AudioManager.STREAM_RING, true);
    amanager.setStreamMute(AudioManager.STREAM_SYSTEM, true);
    amanager.setStreamMute(AudioManager.STREAM_DTMF, true);
    amanager.setStreamMute(AudioManager.STREAM_MUSIC, true);
    amanager.setStreamMute(AudioManager.STREAM_VOICE_CALL, true);
    //disables vibrate and sound of ringer
    amanager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
    //fakes voice call...changes alarm to single tone+vibrate
    amanager.setMode(AudioManager.MODE_IN_CALL);
    amanager.setStreamSolo(AudioManager.STREAM_VOICE_CALL, true);

This works for disabling music and incoming calls, but, as noted in the comments, the android's built-in alarm clock app is still able to produce sound and vibration.

Does anyone know how to truly disable ALL sound and vibrations? Or venture a guess as to why the alarm clock app seems to by bypassing the audio streams?

Answer 1

setStreamMute did not work for me to mute the alarm, but using setStreamVolume for STREAM_ALARM setting volume to zero did. It is necessary to restore the alarm volume afterwards.

For example like this:

AudioManager manager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);    
manager.setStreamVolume(AudioManager.STREAM_ALARM, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
