5.1 Connect Dolby surround correctly?

to
- in PlayStation
1

Half the following problem. We have a LG TV and a 5.1 Dolby system (bought separately). Now when I watch TV or watch DVDs, I only get the sound from the fronbox and the woofer. The back boxes don't go.
've already set the TV under Settings that the output device is a Dolby system. The system is connected to the television with an optical cable. DVD player with hdmi to the TV.
how I drove everything over the PS4 (with the optical cable) it worked perfectly. So PlayStation with optical cable connected to the system and with hdmi to TV. PS4 is no longer available.
Ps: yes all boxes are connected correctly.

I've already tried to set the various sound effects on the Dolby, all without success. For example, game, cinema, natural, etc. The sound always comes from the front box.

do I have a mistake when connecting Dolby to TV or something similar? Aja television we do via A1 TV again an extra device which goes directly to television with hdmi.

I think you have to activate the surround speakers in the TV menu. Try setting DTS and look for the room settings.
