react-native-webrtc IOS: Mic is enabled even if only consuming

[yagiz basaran]

Hey,
I got the library to work ('react-native-webrtc'), and I can receive an audio stream. But on iOS, the mic permission is turned on and I can see the orange dot in the top right corner of the screen saying it’s recording, but it shouldn’t. I just want to watch/listen to the stream, it should not be activated.

Any idea how to avoid this? I think it’s causing an issue with the sound quality, the sound is produced by the call speaker and not normal speakers. And when I use my bluetooth earphones, the sound quality is super low since it’s also using the bluetooth mic at the same time (even if I don’t use them).

Any idea?
Regards

It is WAI since WebRTC is designed for full-duplex as is but you can create your own ADM and change it if you like. See https://issues.webrtc.org/u/1/issues/42230897?pli=1.

FTR, the orange dot does not mean that audio is recorded but that the microphone device is opened. It will be enabled even if you mute the microphone. WebRTC does not implement a "deep mute" today where all recording resources are released when muted since it comes with drawbacks such as potential glitches when started again, risk for initial echo etc.

Mr. Andreasson, thank you for your answer, I will look up to your suggestion as soon as possible. However, regarding to your second paragraph I've a follow up, I was testing on Zoom the other day. If Im not wrong Zoom also uses WebRTC architecture. Result is, when Im in a Zoom call and if I am not muted I see that orange indicator which is normal, but when I mute myself I see that orange dot is gone. I was wondering how did they achieve it and can I do something similar to that.
Yours sincerely,
Yagiz

I can't say exactly how Zoom is implemented but I would assume that only their Web-based client uses pure WebRTC and that the native client has its own unique implementation.
