I just completed the coding. I'll PM you a link to MMH 4.0.8 with these changes.
New Feature:
Remix Channel Layout Tool: Added new option to 'Move Quad rear channels to rear of 7.1 file'
Changes:
Remix Channel Layout Tool: User Defined Remix - increased max number of Channels to 8 (to support 7.1)
Could you please kindly test and provide feedback? If all looks good I'll publish the update.
No rush, when you get a chance to test.
Outstanding information @AYanguas , thank you !It is a "known feature' + 'known bug' of the DTS decoder, at least in Denon.
1) DTS decoder 'copies' the Surround channels to the Surround back channels in an attempt to image the sound between each pair sides of surrounds to emulate the supposed position angle that a 5.1 would have with surrounds more at the rear, instead of surround sides location at 90º that is more usual in a 7.1 config. It also compensates for the two speaker sound level to have same level.
If you careful listen near the speakers, check that they sound the same and not different content as when 'upmixing'. THIS is the 'feature'
2) The display shows the Height speakers active, but really no sound goes to them. THIS is the 'bug' but only at the display pannel. You could check if height speakers are really silent.
3) What is new for me, because I never notice with DTS 4.0, is the display Center Speaker active. Perhaps is also a 'display bug' and the Center channel is silent.
So, in summary, it is a good implementation of DTS 5.1 playing in a 7.1 system to sound as if you had a 5.1 speakers system. Only display 'bug' keep lighting the rest of speakers, but they are silent (pending check the Center Channel).
When you select a PCM track in a Bluray instead of the DTS track this does not happen as it is not the DTS decoder working. You should have then available the Sound Option of Multichannel to get only the input channels from the signal (plus the SUB for bass management).
Reviving this 3 year old post - I have had success with 8 channel .wav files instead of FLACs for my Oppo 203. However, the 2 channels aren't sent to the front height, they mix in with the rear surrounds.There's quite a few reports the Oppos won't play 7.1 from FLAC from a USB.
You can use AudioMuxer to convert the 7.1 FLACs to MKV. The 7.1 MKV will play from a USB on the Oppo.
I actually have two different speaker manager setups. 7.1.4 vs everything else. Precisely because of the side vs rear faux pas.How do you play Quad mixes that usually have too much discrete content in the two rear channels, if you have a 7.1.4 home cinema rig?
...
Bummer - 7 months and nobody has an answer for this. I have bought an RZ70 and have been listening to a bunch of quad content on my 5.1, but I am going to a 7.1.4 and I think I might have an issue as well!Does anyone have experience using a oppo 205 into an Onkyo TX-RZR50? I have a four pack of the new Rhino Quad recordings and would prefer not to change my HT settings ...I have 7.1.2 now the rear surround on my sides and the back surrounds on the ceiling are about equidistant from the listening position...the atmos are on top of the front speakers, facing up at an angle. Is there a good setting on the Oppo to just output 4 channel?

I'm liable to start a sh*tstorm of dissent, but I will poke my head up above the wall to make an observation and a modest proposal to your hypothetical problem.
In my listening room, the sweet spot is dead center.
There is nowhere to put "side surrounds" in the Atmos location, because there are doors on each side wall.
When setting up my room originally for 5.1, I experimented with the rear placements, but found they work best in the rear corners. The fronts do better in the corners as well, with a full-range center, for a wider sound field than the accepted 30 degree.
When I upgraded to 7.1, I tried it again, but hearing my treasured quads in a horseshoe sound field at my elbows rather than a square behind me ended quickly & decisively.
My solution was to use the guide in my old used Yamaha AVR manual to return my rear surrounds to the corners in quad configuration, and space the back surrounds equally across the back wall, approximately like the diagram below.
All the speakers are properly toed-in to the sweet spot.
The four ceiling speakers tilted & toed-in similarly in a tighter square.
All I'm saying is it works for me, every space is different, especially with a couch against the back wall.
I'm here to listen the way I like, not mix to the Atmos spec.
I am not going to have a separate quad room, or rig up a switch box to move the rear quad signals from sides to back.
Another thing to consider, as has been discussed in other threads, is depending on your space, two extra "back" surround channels may not gain much advantage over a properly calibrated 5.1.4 rig, depending on the main listening location.
Just my two cents, not advocating that my way is better for anyone else, simply that everything is a compromise.
YMMV![]()

I would rather keep all materials in their original formats.The ultimate 'hands free' solution is to convert all one's 4.x/5.x files to 7.x. Padded with blank channels just like when converting 4.0 to 5.1.
The -ac 8 command in ffmpeg does it simply. I haven't taken the plunge yet and batch converted my whole archive but I think I'm going to. Blank channels are free (zero extra space) with flac.
Haha! Are you being facetious? Where do you land between those polar opposites?I would rather keep all materials in their original formats.
I might matrix some of the discrete material so I can play it on my other systems.
