iOS no sound after setActive

we integrated jisti-meet to our ios app, but after hangup, there is a red bar at the top.

we tried below disableAudio to remove red bar after handup and enableAudio before rejoining a meeting.
the issue is after rejoin, the participants can not hear each other.

-(void) disableAudio {
//[[RTCAudioSession sharedInstance] setIsAudioEnabled:NO];
//[[RTCAudioSession sharedInstance] setUseManualAudio:NO];
[[AVAudioSession sharedInstance] setActive:NO withOptions:AVAudioSessionSetActiveOptionNotifyOthersOnDeactivation error:nil];

-(void) enableAudio {
[[AVAudioSession sharedInstance] setActive:YES error:nil];
//[[RTCAudioSession sharedInstance] setUseManualAudio:YES];
//[[RTCAudioSession sharedInstance] setIsAudioEnabled:YES];

What do you do after hangup? Do you get the condeferenceEnded delegate method called?

here is how it occurs
1 join a meeting ,everything is good ,haveing sound.
2 handup to exit
3 there is another function using AVAudioRecorder to record voide and share to others but it calles [[AVAudioSession sharedInstance]setActive:NO err:&err] at the end.
4 join a meeting again,issus happens,the participants can not hear each other.

the issus should be caused by #3 setActive:NO and we want to know how to fix it in #4.

Could you give us some help ?

Thank you very much.

Have a good day.

hello, could you give us some suggestions please ?


HI @frank. To be honest I have no idea how to deal with that. You are interfering with the AVAudioSession which the WebRTC library is using… can you avoid calling setActive:NO in your recorder?

I think I might have solved your problem… by mistake :stuck_out_tongue: Can you please build the SDK with the following patch applied?

thanks for your help .but there is the issue yet.

below steps will reproduce the issue

  1. join a meeting (thing goes well here), then click handup to exit

  2. other module in same application call below
    AVAudioSession *session = [AVAudioSession sharedInstance];
    [session setActive:NO withOptions:AVAudioSessionSetActiveOptionNotifyOthersOnDeactivation error:&error];

  3. join a new meeting, then participants can not hear each other

hope get your help again

thank you very much.

We have another issue need your help , we have found that jitsi use the bigger data traffic than other solutions , for instance ,there are 6 persons in one room last 20mins ,it will cost 600MB data traffic of per person ,

we have tried to find some solutions to decrease data used ,like reduce the resolutions and fps, but seems no help .

Could you give us some help or suggestions?

In addition ,we have read some answers in stackoverflow below:

Do you think that it is possible ?

Hope get your reply and many thanks.

Have a nice day.

In iOS we ignore the resolution constraints and use 720p always. You can change those here:

@frank @saghul I’m not using the same jisti-meet library but I also face the same issue. How to fix this problem?
