Muting audio in an Adobe Connect meeting is one of the most important things to do to prevent audio feedback, especially the “killer” kind that can so disrupt a meeting as to lead to ruin.
It is a simple thing to do. First, you should always, always run your audio setup wizard in Adobe Connect before you participate in the meeting. That means you should log in, in advance, when the meeting is available and run the wizard.
Then, simply click the white microphone icon to start your audio. The mic icon will turn green, and you will see a “sound wave” animation showing you are sending audio.
To mute: just click the green mic icon so that a slash mark shows across it.
To unmute: Click again to remove the slash mark and therefore unmute the microphone.
The following animation depicts the two instructions above.
