UC, Lync Web App, Manage Audio, Video and Participant Settings in Lync Web App

On this page, you can learn how to manage meeting audio and video settings during a Lync meeting.

You can manage meeting audio and video settings during a meeting. Some options are available to all participants while some others are available to presenters only.

What do you want to manage during a meeting?

Manage meeting audio

NOTE:  In order to make full use of Skype for Business at Illinois' various services, you must use a device certified for Skype for BusinessFor recommendations, see Skype for Business, Devices and Equipment .

WARNING:  If you choose a device that is NOT on the Equipment for UC at Illinois list, it may violate campus policy. All campus-owned computing equipment bought after January 1, 2012 that will be used to make phone calls must be able to support 9-1-1 services as provided by the campus VoIP solution. 

When you connect to the meeting audio using one of the audio devices connected to your computer, you’ll see audio controls when you point to or select the Phone icon at the bottom left of the meeting window.

To do this task Do this action
Adjust the volume Move the volume indicator to the right or left.
Change your audio device Select the device you want from the list of audio devices displayed.
Mute your audio Select Mute.
Unmute your audio Select Unmute.
Put the call on hold Select Hold Call.
Resume the call Select Resume Call.

Additionally, if you are a presenter, you can mute a specific participant or all participants.

To mute a specific participant, do one of the following:

  • Select the mic icon on top of the participant’s picture or video.
  • Right-click with a mouse, or press and hold the participant’s name in the participant list and select Mute.

<To mute all participants, select the People icon > ACTIONS tab > Mute Audience.


  • You can instantly change your audio and video device during a meeting.
  • You can also use the Mute button on your audio device to mute or unmute your audio. However, with some Lync certified devices such as Aries, the muting initiated from the device doesn’t get transmitted to Lync Web App and vice versa. This is because the software for the phone and Lync Web App can’t communicate with each other.

Manage meeting video

You don’t need a camera to see the video shared by another participant. However, if your system administrator has enabled video sharing, you’ll need a camera connected to your computer to share your video with other meeting participants after you join the meeting. After your camera is installed, you can manage your video sharing options.

To do this task Do this action
Preview your video Point your cursor to the Video icon, but don’t select it.
Start your video Select the Video icon and select Start My Video.
Stop your video Select the Video icon and select Stop My Video.
Stop sending and receiving video Select the Video icon and select Leave Video.
Minimize your video or picture Select the down arrow above the picture. This minimizes your video or picture on your computer, but other participants will still see it on their computers.
Maximize your video or picture Select the up arrow that replaced the picture.
Change your video device Select the Gear Icon > Options > Video device. Select the drop-down arrow to select the camera you want and select OK.

 NOTE:   In a meeting with multiple participants and everyone sharing their video, you can see all the videos only if your system administrator has enabled viewing multiple video streams.

Speaker View Displays the picture or video of only the current speaker. However, if the speaker is sharing content, this view displays only the shared content.
Presentation View Displays only the content shared in the meeting. This option is available only when content is being shared. When a sharing session starts, the display automatically changes to this view.
