i got a pioneer 668 today. also got a nice digi coax and stereo phono's to connect the 2 up (before i was using optical for movies and music) i get 2 chan stereo fine. but no DD/DTS (/me looks at the vanwel post, yes i see it, but no answer there as its not the same ) i have tried every setting on the dvd player.. well im pretty sure i have. i have tried another dvd player. i have also tried other leads. all i get is the chan audio being turned into pro logic by the A2. so it all points to the yamaha a2 i would assume. i have played with the settings on the A2 but havent been able to get any DD output the 2 channel stereo leads are connected from the dvd stereo output to the dvd stereo input on the A2. the digital coax is on the digi coax output on the pioneer and the coax digi input on the yamaha A2 the A2's DVD input is currently set to auto and it is detecting analog. (i get no sound from the other input settings) the pioneer 668 settings are as follows. Audio DRC : off Virtual surround : off channel level : fix Digital out : on Dolby digital out : on DTS out : on Linear pcm out : down sample on MPEG : MPEG > pcm those are all the the above are the default settings i think.. i reverted back due to none of my changes sorting the problem.. anyone able to shed some light on this?
