if you find the audio element in the html and add the controls attribute i'd imagine it would give you a scrubber and some volume controls. i don't have juto so can't check, but you should look for something like
Code:
<audio>
<source src="your_audio_file.mp4" type="audio/mpeg">
</audio>
and change it to
Code:
<audio controls>
<source src="your_audio_file.mp4" type="audio/mpeg">
</audio>
