Hello, I recently purchased an used JX35 with DVD system. When I play a DVD I am supposed to get audio trough the wireless headsets, as well from the wired audio output at the rear console of the second row; but audio won't come out. When I plug and external device in one of the input, audio comes fine trough the wireless headphones. Is there an additional setting for the DVD audio, so I can hear what is playing via headphones? The screen panel shows the headphones icon on it.
Thank you
Oscar.
