Hmmm,
Just re-ran the Channel Config...started again with both Dolby True HD and DTS-MA HD, no sub output. Ran the 96khz/24 bit/5.1 ch/LPCM test...sub now gets a signal and responds! Went through the rest of the menu and returned to Dolby True HD..sub now works with it. It's even working now on DTS-MA HD, but the volume still needs to be cranked to -11 to be even close to the same spl as -35 db on everything else. Still don't get that. BTW, played the audio cuts on the AIX disc...really spectacular on both audio and video.
