Hi there,I'm having a few problems getting any sound out of my BDP-S4100 blu-ray player via it's coaxial output... I'm sending the coaxial output to my stereo amplifier via a DAC as my amplifier only has analog inputs.My stereo amplifier is a Rotel RA-04.The DAC I'm using:I've sent the line out from the DAC to my aux inputs on my stereo amplifier. Set the 'input select' on the DAC to '2' as this is the selection needed for coaxial inputs. I have made all the necessary adjustments in the blu-ray players settings as per the instructions in the manual. Went to play a movie on a blu-ray disc and I can't get any sound out of my stereo speakers.I can get sound out of my LG 26LK330U internal speakers as I have connected the TV to the blu-ray player via HDMI. Even when I connect the TV to my stereo amp with an optical cable from the TV's optical audio output via the DAC I can't get any sound out of my stereo speakers either.Anyone know why this could be the case/how to resolve this?Thanks.
