Found this thread actually looking for how to have a player widget on a notebook, ended up with this after a python example:
using WAV
wavwrite(0.4*rand(2000, 2), "example2.wav", Fs=44100.0)
audioplayer(filepath) = """
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Simple Test</title>
</head>
<body>
<audio controls="controls" style="width:600px" >
<source src="$filepath" type="audio/wav" />
Your browser does not support the audio element.
</audio>
</body>
"""
display("text/html", audioplayer("example2.wav"))
