Bug 236785

Safari 15.3 on Monterey (not happening on Safari 15.1 and 15.4 dev preview) Steps to reproduce: - create a peerconnection (subscribe only) to a remote audio and video. - create a video AND audio HTMLelements and apply as srcObj the audio + video stream just subscribed. - set the videoHtmlElement as muted = true observe: - everything works as expected, I can hear remote stream from the audio tag and see the remote video in the video tag (i CANNOT hear, as expected, the audio track from the video tag since it's muted) what breaks: - i call getUsermedia({audio: true, video: true}) in the same page observe: - I now hear the remote side twice what happened: - the video element showing the remote stream "unmuted" itself, despite the fact that $0.muted is showing true proof: - set the video element to muted= false and then muted = true again and the double audio disappears. Workaround: - create a new mediaStream with only a track (one for video and one for audio) and assign them to the HTMLElement. But this breaks Safari 13 since MediaStreamTrack.clone() is broken :( HALP TLDR: - calling getUserMedia unmute all video tags in the page
