            Bug ID: 226921
           Summary: MediaDevices devicechange event loop
           Product: WebKit
           Version: Safari 14
          Hardware: iPhone / iPad
                OS: iOS 14
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Media
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: the.jon.mudrick at gmail.com

In safari on iOS 14.6, the navigator.mediaDevices devicechange event (https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/devicechange_event) gets called repeatedly as long as a bluetooth headset is connected to the iOS device. The event stops firing as soon as the bluetooth headset is disconnected. Observed with AirPods Pro and Bose QC35 connected to iPhone.

This may have started with the release of iOS 14.5. That's the first time we started hearing customer complaints about airpods with our webRTC implementation.
