Equipement: samsung hw-N550 3.1ch SoundBar, vero 4k+, sony TV kd43xf2096, linked with HDMI, cec disabled. Passthrough is working, I tried fixed/best match/optimized on system/audio settings, still showing.
This information is shown in the “audio settings osd” when I chose an audio stream like original version or dubbed voices.
I have the settings you wrote. and I have tried 2.0 and 5.1, I noticed no change when passthrough is on. But if passthrough is off I have to stick to 2.0 channels.
5.1 side is the standard way of Dolby and DTS to encode 5.1 channels. It means that the rear channels of a 5.1 stream should be placed on the surround side channels of a 7.1 setup. What you see there is to be expected, @mrtnn
We’ve had an extensive discussion about this when we tried to figure out where to place the surround channels of a 5.1 PCM file when outputting it in a 7.1 container (quite a long time ago now). Dolby and DTS want a non-upmixed 5.1 track to be played on the fronts and side backs only, not the surround back channels.
Yeah, OSMC does it right and puts 5.1 into the side of 7.1 regardless of the whether the “hint” says side or rear, because that hint is often unreliable.
Nope, that’s just what’s in the metadata of the stream. If you don’t passthough, OSMC figures out how to put the PCM, and your AVR then does whatever with it, depending on its settings. If you do passthrough, your AVR does all the decision making.
In general, AVRs often respect the hint of “side” or “rear”, while OSMC does not, and should not, since, again, it’s often incorrect.
Let’s not get into 7.1 DTS-HD MA formats that include hints similar to Atmos or DTS:X 3D audio, so that if you have a system with more than 7.1 speakers, an AVR could route the sound to the best location (overhead, rear, side, high front, etc.). Again, these are often wrong, and have been seen in the wild on commercial BluRay disks.
