Blu-ray lossless audio connection problems

[sathron]

I have an older (8 years old), but very high end Home Theater Receiver, the Denon AVR-5800. I absolutely love it, and am not yet willing to part with it...the one drawback is that it does not have HDMI inputs, or the ability to decode the new lossless audio encoded on Blu-Ray (DTS-HDMA, Doby TrueHD, etc..)So to get past this, I replaced my Sony Blu-ray (BDP-S300) player with a Pioneer (BDP-320) which has internal decoders to go along with 7.1 analog outputs. I hooked up the Pioneer BD player to the external 7.1 analog inputs on my Denon. All worked great, except audio to my subwoofer. I know the internal processing of the Denon was no longer operational in this set up (for watching Blu-Ray and standard DVD's), thus used the internal settings on the Pioneer for audio adjustments, including speaker set-up for the subwoofer volume and crossover. Here's where I ran into the problem....there is NO SIGNAL passed through to the subwoofer (I have my velodyne HGS-12 sub hooked up to the subwoofer pre-out on my Denon). I believe I've tried every option...switched the cables, tried the Ext 2 input on the Denon...yet no LFE response? I did run the sub out of the BD player directly to the sub itself...it works, so I know it's not a faulty "sub out" on the BD player. If I did keep it hooked up that way though, it would eliminate the sub's internal crossover, and would not allow me to use the sub for listening to other sources (DirecTV, etc..) I feel I may be missing a setting on the Denon receiver, and that the signal is not passed from the Ext-In to the Pre-out for the subwoofer? When I do switch the output on the Pioneer BD player back to the Optical Audio output (thus using the Denon's internal decoding for the standard DTS, DTS-ES, Dolby 5.1, Dolby Surround EX) it works fine. I was so pumped for the true Hi-Def Audio and Video experience though

Any help or advice would be greatly appreciated!! I would love to watch Transformers 2 in DTS-HDMA

Thanks in advance!
