I recently picked up an oppo 103. I have it plugged into my Onkyo NR656. I have no sound. No cd no usb and no dvd. I have it plugged into my onkyo with HDMI. Tried two diff ones. Neither working. I have update from 7/13 on it. I think it’s 4819 something like that. I bought this to play my SACD. Not sure if updating will affect anything or will I lose anything.
