            Bug ID: 225880
           Summary: Stuttering audio with WebRTC + WebAudio in latest iOS
                    14.5.1
           Product: WebKit
           Version: Safari 14
          Hardware: iPhone / iPad
                OS: iOS 14
            Status: NEW
          Severity: Critical
          Priority: P2
         Component: WebRTC
          Assignee: webkit-unassigned at lists.webkit.org

When calling getUserMedia() while playing audio via WebAudio on iPhone/iOS-14.5.1, 
the getUserMedia audio stream sent to the remote client is choppy, with roughly a blank tone every second.

If you add a <audio> element playing silent audio, you get faster choppiness,
around 4-5 times per seconds.

The mix WebRTC + WebAudio is deadly on iOS, makes Safari browser unusable.
The exact same code works perfectly on Chrome, Firefox, and Safari Mac.
