Is there a way to detect when a participant has muted their audio in opentok.js?

I went through the publisher docs which has the methods publishVideo(value) and publishAudio(value). Corresponding to the video part, the subscriber receives the event videoDisabled or videoEnabled with the reason publishVideo which allows me to determine whether the subscribed participant has intentionally turned off their video or not, but I can't find something similar for audio such as audioDisabled or audioEnabled. audioBlocked event supposedly only covers blocks by browser's autoplay policy: Dispatched when the subscriber's audio is blocked because of the browser's autoplay policy.

The audioLevelUpdated event provides the current audio level, but that could just be silence, not an intentional mute, so that doesn't look ideal for this purpose.

I want to show a audio muted icon on the subscribed participants element when they have intentionally turned off their audio by calling publishAudio() method. How can that be achieved?

Referenced docs:

Set OTSubscriberKitNetworkStatsDelegate to subscriber as

subscriber.networkStatsDelegate = self

Then you can call the below function to get simultaneous changes on subscribers' microphone status

func subscriber(_ subscriber: OTSubscriberKit, audioNetworkStatsUpdated stats: OTSubscriberKitAudioNetworkStats) {
         // call stream.hasAudio 
     }

You can also check from opentok audioNetworkStatsUpdated

Each stream has an hasAudio attribute that returns false if the user's audio is muted or their microphone is muted. Similarly, streams also have a hasVideo attribute. You can reference the stream docs at https://tokbox.com/developer/sdks/js/reference/Stream.html.

I personally use it like so:

session.streams.forEach((stream) => {
    const name = stream.name;
    const video = stream.hasVideo;
    const audio = stream.hasAudio;
});

You can listen for these changes with the session.on('streamPropertyChanged') event: https://tokbox.com/developer/sdks/js/reference/StreamPropertyChangedEvent.html

Hav u tried audioLevelUpdated and checking the level of audio

If level is 0 then its muted.

https://tokbox.com/developer/sdks/js/reference/Subscriber.html#getAudioVolume

So steps are listen audioLevelUpdated and check AudioVolume, audio volume should get u the subscriber level point.
