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 1843660 1 ap 2022-02-18 14:49:38 -0800 > not happening on Safari 15.1 and 15.4 dev preview While I'm not an expert in this area, not happening with 15.4 dev preview would indicate that this is already fixed in WebKit code base. 1845376 2 webkit-bug-importer 2022-02-23 15:43:22 -0800 <rdar://problem/89382851> 1877932 3 bfulgham 2022-06-23 15:33:10 -0700 We believe this is resolved in Safari 15.4 (and newer).
