Moin again because of home theater system, have a cable found but do not know if it has something to do with it and generally do not know what it brings, what brings it?

Have the cable found (see picture) and do not know what it brings
I have it now on the system ((HT-H4550R)
and in my Ps4, have the attitude in ps4 already tried a few times but notice no difference
That's why I would like to know what it brings

There was still something with audio in etc

Looks like an optical audio cable. Well suited to transfer sound in good quality, if the playback devices can implement this.

Looks like a fiber optic cable. Theoretically, you have a better sound quality.

Now that you write it, you realize that the quality has gotten a bit better, but unfortunately that did not change my problem as hoped that all speakers will run on music, but many thanks

Many Thanks.

So on my home cinema device (logitech something, I'm just too lazy to look closely, because I would have to get up to it) you can switch between stereo and 5.1 or "3D".
