**Description**  
I have microphone permissions and I await startAudio after starting meeting. It unmutes the user. After that if I try to mute user, 1/10 times it gives me an error, INVALID\_OPERATION: no audio joined. How can I confirm if audio is joined before muting the user ?

**Browser Console Error**  
{type: ‘INVALID\_OPERATION’, reason: ‘no audio joined’}

**Which Web Video SDK version?**  
Video SDK- 1.5.5

            user.userId !== zmClient.current.getCurrentUserInfo().userId &&

@sprinklrqa4 ,

Seems like there is a possibility out of the 1/10 times, the startAudio() has not completed yet.

An alternative implementation would be to use \* [event\_current\_audio\_change](https://marketplacefront.zoom.us/sdk/custom/web/modules.html#event_current_audio_change) to listen for users to successfully join audio before proceeding to mute them

Hi  
I have the same problem as the author of this topic.

According to the documentation, startAudio starts this way ( i.e. I need to wait for some events):

```auto
await client.init();
await client.join(topic, signature, username, password);
const stream = client.getMediaStream();
await stream.startAudio();

```

There is another version of the implementation for safari. I used to have it implemented this way, but problems began to arise with this method too:

```auto
// Safari browser is different:

let audioDecode, audioEncode;
// wait until the encoding and decoding process is ready for the audio
client.on("media-sdk-change", (payload) => {
   const { action, type, result } = payload;
   if (type === "audio" && result === "success") {
     if (action === "encode") {
       audioEncode = true;
     } else if (action === "decode") {
       audioDecode = true;
     }
     if (audioDecode && audioEncode) {
       try {
         // start audio automatically in Safari
         stream.startAudio({ autoStartAudioInSafari: true });
       } catch (err) {
         console.warn(err);
       }
     }
   }
 });

 // Start audio in 'click' callback in Safari
 joinAudioButton.addEventListener("click", () => {
   if (audioDecode && audioDecode) {
     try {
       stream.startAudio();
     } catch (err) {
        console.warn(err);
     }
   }
 });

```

But the problem with this method is that after disconnecting from the session and reconnecting, the necessary events (media-sdk-change) do not come, but only a part of them comes.

Each time the threads are initialized, 2 events (encoding and decoding) should occur in the session for each of the threads: audio, video, screen sharing. A total of 6 events should come, but when reconnecting to a session without reloading the page, only 4 come, and there are not even any events with audio data.

I tried both of these methods but could not find an optimal solution to this problem.  
In both cases, I wait for startAudio to execute and, upon successful completion, I call muteAudio:

```auto
await stream.startAudio();
await stream.muteAudio();

```

A participant on macbooks regularly 1/5 this problem. They just enter the conference and their microphone cannot be automatically muted.

@chunsiong.zoom, hi!  
My logs show that this trigger is triggered even before startAudio occurs. Are you sure this is how it should be?

In addition, I have tested the method you proposed, but the problem, unfortunately, remains =(

Hey @efron.vit @sprinklrqa4

Thanks for your feedback.

We will improve the timing of `startAudio` and `muteAudio` in the next version.

Thanks  
Vic

Hey @efron.vit

Yes. We improved the timing of `stream.startAudio`. It’s the root cause of this issue.

Thanks
