I have a 7.1 system but it seems that the 1098 doesn't want to send any sound to my center rear left & right speakers. All 7 channels of my amps are fine. In the setup of the 1098 I have indicated I have 2 small center rear speakers. I have all other speakers set to small as well. When I play the system test tones I get the normal static tone in both of the center rears indicating that they are receiving information. When I play 7 -channel music, no sound in the rears. Dolby Digital EX or Dolby Digital + XS or DTS ES or DTS + XS - nothing in the center rears. Any suggestions? I have tried adjusting the input level in the center rears to max, still no sound.
