looking for something cheapo to monitor the audio, you can go to your local electronic store and buy this adapter:
of course the av out ain´t live, that´s why is a pseudo, but during playback, at least with the factory settings it works, with hacked settings a haven´t tested it, but as Vitaliy said on the ptool that the audio avobe 192kbps will not playback in camera, probably this cheapo workaround ain´t going to work (my battery is running low to test this) hope it helps someone
