Hi Team,

While going through Youtube, I came across this random Youtube video, where at the start of the video, I hear pop from MacBook speaker while playing video using Safari but it does not happen when using Chrome Canary 112 and Firefox Nightly 111.

Youtube Video Link - https://www.youtube.com/watch?v=8AUBIaLsmDQ

Test Safari versions - Safari 16.3, STP162 and WebKit ToT (259843@main - some test patches, which I testing locally but none of them media related)

Just wanted to raise it so if it is something reproducible by others then we can track it and fix it.

- I checked and I don't have any Youtube Site specific hacks disabled.
- I disabled all Adblock extensions and used even private window and still got pop-up in speaker (using laptop speaker).

Thanks!
