Sorry I can`t help you, but I also have a problem with the audio output from my dansai.
My dansai is connected via phono plugs to my cambridge amp, also by scart to my TV. I have also connected my video via phono plugs to the amp and via scart to the TV.
When the TV is switched on / or left in standby the sound quality from DVD, CD, CD-R is excellent. However if I listen to music via the DVD and amp only with the TV switched off the sound is muffled and poor. I have a pair of book case size speakers placed about 12 inches either side of the TV.
Can anybody help or explain.
Many thanks.
