AVR in question is a Denon X4400H
It's a 9.1(2 front height and 2 rear height) setup that I used to use for Auro-3D playback. Due to a recent move and just now recently getting set back up, it's been awhile(a year or so) since I've tried using one of the upmix algorithms on the AVR(almost always Auro-3D)
Symptoms:
1. Stereo setting works fine and plays through the FR, FL and Subs properly
2. Any sort of upmix algorithm only plays through FR, FL and the two front height speakers. Center channel, both side surrounds, and both rear heights are silent. This is consistent amongst all upmix algorithms(Auro, Dolby, DTX, etc.).
3. Multi Channel Stereo Setting correctly plays through all 9 speakers
Manual Setting Config under the AVRs settings are attached
My thoughts so far in my attempts to debug the issue
1. The fact that all speakers play sound in the multi channel stereo setting means that everything is most likely properly connected
2. The fact that I'm able to select the Auro-3D setting at all means that the (silent) back height, center, and side surrounds channel speakers are being detected by the AVR
3. If I disconnect (for example) the rear height speakers, I lose the option to even select Auro-3D, which further confirms what I thought in #2
4. The fact that the front heights are being correctly upmixed means that the feature is working in some capacity. If the upmixer in the AVR were broken, I would expect the surround modes to not work at all.
Any ideas or avenues I should pursue in trying to debug this issue? Unfortunately, I don't have another 9.1 capable AVR. All suggestions are welcome.
