5.1 channel via Optical Audio cable

[Oleg_D]

Hello, I have such situation.

I have Apple TV 4K which is connected to TV KD55XE7096 to HDMI/ARC (otherwise 4K is not streaming from Apple TV) and Home Theater HT-RT4 which is connected via Optical Audio cable. The problem is that I do not feel that it plays 5.1 surround. I guess all Sony products support Dolby Digital, so there should not be any problem. 

But still on the top bar, which temporary appears is still showing (Stereo 3840x2160) and I suppose it should be change according to output?

Can you help me with this? Thanks in advance!
