Any ideas why output audio volume should not be adjusted by this code? I am developing for Vuzix M400 and I am using Vonage Video API (Tokbox).

It works just fine on ordinary android smartphones so I searched Vuzix documentation and found that AudioManager is right way to adjust volume on this device.

    AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);    
    audioManager.adjustStreamVolume(AudioManager.STREAM_VOICE_CALL, AudioManager.ADJUST_RAISE, AudioManager.FLAG_SHOW_UI);

I have tried:

  • Set volume control stream on start of activity setVolumeControlStream(AudioManager.STREAM_VOICE_CALL);

  • Use Tokboxes CustomAudioDevice

    CustomAudioDevice customAudioDevice = new CustomAudioDevice(MainActivity.this); AudioDeviceManager.setAudioDevice(customAudioDevice);

  • Use adjustVolume instead of adjustStreamVolume
