            Bug ID: 205682
           Summary: Changing output device sample rate AnalyserNode stops
                    and source is in invalid state
           Product: WebKit
           Version: Safari 13
          Hardware: All
                OS: macOS 10.13
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Audio
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: arturs.valenieks at gmail.com

Attaching analyser node to an audio stream and then changing output sample rate (in MIDI settings, changing output device or input device), stops updating analyser nodes internal state, meaning it always returns same value, the last value before changing sample rate. When sample rate is changed back to initial one analyser recovers and keeps updating its internal state. Besides that I failed to attach new analyser node to stream by disconnecting previous or attaching new AudioContext.
