Detect if html5 audio element supports volume setting

[Pandabehr]

Basically create audio tags, set volume to random number under 1 (1 is highest)
If its the volume is the same as before it doesnt support it
code gives an alert if not supported

var audio = PB.$('<audio></audio>'),
    temp = audio[0].volume;
audio[0].volume = ((temp / 5) > 0)? (temp / 5): 0.1;
if(audio[0].volume == temp) { alert('Nope'); }
audio.remove();
