Repro URL: <a href="https://downloads.scirra.com/labs/audioCodecTests/">https://downloads.scirra.com/labs/audioCodecTests/</a>

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"</pre>
