Similarly, how do I mute an embedded YouTube video?
Just add mute=1 to the src parameter of iframe.
One may also ask, how do I mute an iframe? Just add the button after the iframe and on click mute/unmute the video :) You can only mute HTML5 audio and video elements. An iframe does not have an audio API, so you can't mute anything using JS on that element.
Keeping this in consideration, can you mute part of a video?
Mute video
Right-click the video clip and select Mute. This will silence the audio on the video clip, but not remove the audio for that single clip. To mute the audio of the entire track, you can select the Audio icon to the left of the track to Mute the track. This will silence all of the clips on that single track.
Why do my YouTube videos start muted?
So, the reason why your audio is muted is because there's been a change in how the Youtube and Flash combo works recently. If you do not let your Flash Player store content to your disk, then you will not be able to save any settings and all videos will start muted.
