I host a WAVE-file, which plays fine, it's URL is entered in Mobile Safari directly. Trying to embed it in a simple HTML page shows me a "can't play" icon:
What's wrong with my embed code?
<embed href="http://localhost/test.wav" type="audio/wav"/>
It was a server problem. Apache has a special mode for downloading the file. You need it for embedding the audio, as I posted above.
