Android WebRTC can not mute remote sound on speaker

[quockh...@vnnplus.vn]

Hi,

Are there any ways to mute the remote sound on speaker ?

If I use volume button I can only lower the volume but can not mute the volume.

I use these code to bring sound to speaker :

AudioManager audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
rollBackMode = audioManager.getMode();
audioManager.setMode(AudioManager.MODE_IN_COMMUNICATION);
rollBackSpeakOnPhone = audioManager.isSpeakerphoneOn();
audioManager.setSpeakerphoneOn(true);
rollBackVolumeControl = getVolumeControlStream();
setVolumeControlStream(AudioManager.STREAM_VOICE_CALL);

You can't mute the speaker totally on Android in Comm mode. The idea is that a phone call

should never go totally silent. Hence, the behavior is expected and by design. 

You can however use this private API to mute the speaker completely if required.

Hi,

So are there any ways to change the remote sound volumes programmatically using java api?

The API shown earlier is a Java API and I think it will do what you asked for.

Or am I missing something?

Hi,

I mean i want to override the onKeyDown function to handling the volume up/down button to change volume of the remote stream.

Can I do it with the webrtc android api ?

No, that is not supported and something that you have to deal with in your app that uses WebRTC instead.
