[Audio] isMicrophoneEnabled is false, but Microphone still recording

[baveku]

the issue is funny
I turn off micro but the received still hear me,
console log:

print("[LIVEKIT][VOLUMES] \(speakers.map({($0.memberID, $0.isMicrophoneEnabled(), $0.audioLevel)}))")

there is the result:

[LIVEKIT][VOLUMES] [(2586, false, 0.125)]

isMicrophoneEnabled = false
audioLevel = 0.125

Why don't we disable the micro module after the microphone is set off?
Livekit still recording when microphone is off

Oh, I'm very stupid :D I call duplicate some function so It's break code,

but I need a solution to disable Microphone module when I mute micro

Hi, thats odd. You called localParticipant.setMicrophone(enabled: false) on participant A, but participant B can still hear ?

[baveku]

I'm sorry, it's my fail
I call track.stop() and localParticipant.setMicrophone(enabled: false) in same time, so it's break logic(Fixed)

I want to ask: when we turn off micro, why is Recorder still working?
(I saw a dotted yellow(microphone is recording) on iOS Statusbar)

@baveku Please unpublish the track to turn off the mic recording indicator.

[baveku]

I mean I use localParticipant.setMicrophone(enabled: false), so I need unpublish track to stop recording, right?

[baveku]

@baveku Please unpublish the track to turn off the mic recording indicator.

I will try this solution.

It works, but why don't we disable audio if the microphone is turnoff?

[hiroshihorie]

You have a good point, initially that was the default behavior.

But we need to switch AVAudioSession.category when mic switches on / off which also causes the volume to change which was confusing.

Therefore we decided not to switch category when mute() / unmute() (which is called internally by setMicrophone(enabled:)) but instead switch category when publish / unpublish.

I think we need to disable audio recorder module, I used Messenger or Google Meet and they disable the recorder when micro turn off.

You are right, this is actually a design flaw in the WebRTC's iOS SDK.
The AudioUnit should be able to switch on / off without category switch required. (ability to toggle mic usage while keeping .playAndRecord category)
Fixing the root cause will be a bit tricky and I don't think I can work on it any time soon.

okey, thank for your support, I solve my problem by your solution.
I still follow Livekit and use it for my production.
I hope Livekit will be more and more perfect. 🥂
