Don't do that. Number of channels *must* be set to 2.0 when using spdif/toslink.
Number of channles is only used for multichannel PCM, which is a HDMI feature.
Passthrough will still work with number of channels set to 2.0.

Thanks for your answer. Now i realise, my downloaded video was Dolby Digital Plus, and my soundbar is only working with Dolby Digital.
So if i set RPI3 --> HDMI (5.1, passtrough, ac3 /Dolbi Digital/) --> Soundbar --> TV and i downloaded free soround music from this site: Free surround music download - 5.1 Dolby Digital "5.1 Surround Test File" and i hear the channels sound in the right places. Front Left --> Font Left.. etc. So the HDMI 5.1 is working now. DONE.

But the spdif... So i missed some details in my first post. In my Libreelec / Kodi settings i couldn't set the channel numbers when is use spdif (HifiDigi+).
I could set if i want to passtrough or not. So is that you said is meaning, i can't passtrough 5.1 channel sound in spdif ?? Or i still don't understand, the whole things? Because i hear the sound with this version: (Sound connection): RPI3 --> Spdif(HifDigi+, passtrough, without ace3 /if i set this option, there is no sound/) --> Soundbar, (Video connection): RPI3 --> HDMI --> TV . But this version i just hear 2.0 sound on my 6 speaker.

Spdif = 2.0 ?

Hi All!

I used my RPI 3 (Libreelec 7.0.2) with an HiFiDigi+ SPDIF soundcard which is a HifiBerry replication. I used it with my Samsung HW-F355 2.1 Soundbar.
It worked perfect. But now i bought a Samsung HW-K550 + Rearkit soundbar, which is an 5.1 sound system.

I changed my audio settings in kodi to 5.1, 5.1 passtrough, and etc. But it didn't work right. I downloaded some 5.1 channel test video, and i always hear the same. When i must hear just the front right, i hear front and rear right, when i must hear the front left i hear front and rear left... and when i must hear subwoffer in the channel test... there isn't any sound....:(

Is someone who tell me what could i do to wokrking the 5.1 with HifiBerry? Or am i misunderstanding, and HifiBerry doesn't have ability to 5.1 sound, or 5.1 passtrough??

A cheked another option: RPI3 (Soundcard HDMI 5.1)--> HDMI cable-- > Samsung HW-K550 --> HDMI cable (ARC) - Samsung TV
But it was the same, i didn't get any true 5.1 sound, when i play the channel test videos.

In SSH i get this:
