            Bug ID: 234840
           Summary: Audio canPlayType() reports false negative for PCM WAV
           Product: WebKit
           Version: Safari 15
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Media
          Assignee: webkit-unassigned at lists.webkit.org

In Safari 15.2, canPlayType() indicates PCM WAV ("audio/wav;codecs=1") is not supported by returning an empty string. However when passing a PCM WAV file to both an <audio> element and Web Audio, it correctly decodes and plays the file.

Observed result: canPlayType() returns empty string
Expected result: canPlayType() to return "maybe" or "probably"
