All outputs are active but you may have to go to the setup to make the digital audio outputs active.
ie I use the main HDMI to watch movie and the second HDMI to a 10" monitor and and analogue audio outs for sacds and cds.
There is no usb output for a dac only sdif or coaxial.
Note: the latest 2012 firmware locks out ISO file playback..... If you play BDISO files don't upgrade. Turn off Auto update in the setup menu.
You can't go back to the firmware because it is not available. Don't know if the firmware recovery disk that comes with the player would work.
