            Bug ID: 243912
           Summary: Certain TikTok sound previews are broken
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Media
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: y_soliman at apple.com

Any TikTok sound generated from an originally uploaded video (not submitted as a separate audio) is not handled properly by our media pipeline.

The issue arises from TikTok making a request for an `audio/mpeg`, while the server responds back with a MIME type of `video/mp4` and response body containing an `mp3` file.

Downloading the file locally, you can see that renaming the file extension to `mp3` and opening it in Safari will play normally.

A fix for this might involve inferring the type separately and falling back to that media type if the initial load is unsuccessful.
