Watching TV via home cinema speakers?

The following question quaelt me for a short time:

Is it possible to watch TV on home cinema loudspeakers?

I would like to buy the Ultima 40 Surround AVR 5.1 home theater set by Teufel. Is it possible with these speakers on my TV set as normal to watch TV, because my TV has broken speakers?

I'll buy the following TV in the very near future, but I also want to enjoy the Teufel speakers (even if it's just stereo), my TV program or Netflix

If the home theater system has a digital or headphone compatible input then that is possible.

According to HP from Teufel, the home cinema system TOS-Link, do you mean that?

For such a question you look in the manual of the home theater system or the AV receiver, there you will find the answer from page 30 on how the TV can be connected:

This is possible via HDMI ARC and optical digital output of the TV, the devil has plenty of connections if it is the version with AV receiver you mean

TOS Link is a fiber optic connection from Toshiba. I do not know if the Sony has too.
