Canon 7D - Audio Monitoring via USB

[ricbi1]

This feature for me is a deal breaker with Magic Lantern. I had it in my 60D and I love it and this with live recording levels make my DSLR a full movie-making device.
Hope it is added soon.
Thanks

After plugging the plug A / V to the USB port, turns off the LCD monitor. Sound in the headphones, but no picture on the screen. Is there a solution ML?
