Hey there everyone, I posted somthing about this in another forum, but I figured I would repost to this forum as it is a subwoofer issue. Basically what is happening, is that I cannot get my sub to work in DTS or DD 5.1 mode. If i play a music cd it works fine. I have plugged the sub into the sub preout on receiver, into the LFE port on the sub, and have also tried the L and R inputs. I have tried adjusting allvolume controls on receiver and subwoofer, and sub power light is on. My setup is connected to my dvd player using a optical cable, dvd player is emitting digital signal and indicator on front of receiver that it has entered its respective mode (dts or DD). My receiver model is Pioneer vsx-d608. I have tried to provide as much information as possible...so...any ideas anyone?
