Why am I not getting any TV sound on my system?

When I play music from my mobile phone or laptop via aux, everything works fine. However, if I want to listen to something on my television via optical cable, I no longer get any sound (although it has already worked on the same TV!)!
With my TV remote control I can turn the system louder, quieter, off, etc. But I don't get any sound.

The sound is in the settings on optical & is on the volume 20!

The optical cable is in "Out" on my television set and in "TV / SAT" on my system.

TV: Samsung GQ60Q65T

System: Pioneer VSX D511

It is connected correctly, the fault can be in the Toslink cable if it was kinked, or the input settings of the Pioneer, check again

The cable was not kinked & the TV recognizes everything.

I've been to the link 20 times already☹️
