On the attendee side there is a volume on/off button. In the Sample App I couldn’t find with function is connected to this button. Could you please guide me.

In TopPanelView.m file there is no audio button:

```
    [self addSubview:self.shrinkBtn];
    [self addSubview:self.cameraSwitchBtn];
    [self addSubview:self.titleLabel];
    [self addSubview:self.leaveBtn];

```

I am using the latest SDK : v4.4.55130.0712

Hi ssaylanc,

Thanks for the post. Are you referring to this icon(in red)?

Hi  
 ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/4/46e206c6f5f52d56b9107e32bad84354a376dc34.png)  
The UI is Zoom UI, Most things are covered by the SDK.

TopPanelView.m is our Sample code to guide How to use a custom UI.

Zoomui is easy to use, but if zoom UI doesn’t fit your needs, you can develop a custom UI.

Murray  
Thanks.

Hi Murray, yes that’s the mute button I am referring. But I couldn’t find the function to mute the audio in the code. Could you please guide me.

Hi [ssaylanc](https://devforum.zoom.us/u/ssaylanc),

The icon you are looking is the icon for switching the loudspeaker on/off. If you would like to control the audio in the code, you can use `muteMyAudio`([https://zoom.github.io/zoom-sdk-ios/category\_mobile\_r\_t\_c\_meeting\_service\_07\_audio\_08.html#afe5b3b9a9339a7afd798d0e1e5265d69](https://zoom.github.io/zoom-sdk-ios/category_mobile_r_t_c_meeting_service_07_audio_08.html#afe5b3b9a9339a7afd798d0e1e5265d69)) to control that.

Hope this helps.Thanks!
