Reopened: Cannot hear anything if app is minimized on iPhone

[r0se9]

I forked this repo and hosted my local server.
Then I noticed that I couldn't hear others voice and other can hear my voice when I minimize the webview on iOS.
It's okay on the desktop but only on mobile. I am using Safari brower on iPhone.
When I was using the former version(v1.x) for livekit, it was okay.
