            Bug ID: 168165
           Summary: Playing a HTML video element corrupts AudioContext
    Classification: Unclassified
           Product: WebKit
           Version: Safari 10
          Hardware: iPhone / iPad
                OS: iOS 10
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Audio
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: ae at instinctive.de

Complete, minimal testcase here:

http://instinctive.de/prolevel/webkit-audio-bug-test.html

Steps to reproduce:
1. Visit the URL.
2. Click the button to have "user interaction" in order to play a sound via WebAudio (it will play once per second from then on). Sound is fine.
3. Play the video.
4. As soon as the video is being played, the sound is either distorted, too fast, or stops working altogether (random)

The video has been rendered with 48 kHz audio, my suspicion is that Webkit doesn't recognize the sample rate change or WebAudio isn't capable of resampling.
