Until now we had been unable to adequately hear dialogue above the sound effects and music, especially with new release DVD's and Blu ray discs, on our new 5.1 surround sound system. We tried connecting the dvd player to the amplifier/receiver via an optical cable, without disconnecting the HDMI cable. When the optical mode was selected on the receiver, the problem was miraculously solved. Speech/dialogue is now loud and clear and proportionate to music and sound effects!! This problem seems to have been a chronic source of frustration for many people on various forums. Has any one else tried this?
