            Bug ID: 212035
           Summary: Audio Drift on Live HLS streams
           Product: WebKit
           Version: Safari 13
          Hardware: Macintosh
                OS: macOS 10.15
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Media
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mfedorenko at fubo.tv

We are experiencing audio drift on Live HLS manifests. 

Safari versions without drift
13.1   (14609.1.20.111.8)
13.1   (13609.1.20.111.8)
13.0.5 (15608.5.11)
13.0.4 (14608.4.9.1.4)

Drift found in:
13.1 (15609.1.20.111.8)
13.2 (15610.1.12.2)

We have a test stream available. We noticed that if you let the stream run long enough, then it will overflow resync with the video for a short time before losing sync again.
