Philips 46PFL5606H / 58 - Change the audio language from English to Polish

Hello. I have a problem.
I bought a Philips 46PFL5606H / 58 TV. I connected it to my cable and set the channels up to my cable. But when there is a movie on a channel, it appears in its original language (e.g. English has no voiceover).

I do as I found in the manual, that is:
Changing the audio language:
You can select an audio language if it is available on the broadcast. Several languages may be available for digital channels.
1. While watching TV, press the OPTIONS button.
2. For digital channels, select [Audio language], select Polish, then press OK

And of course I have a teacher. but when I switch to another channel (because there are commercials) and I want to return to the movie I am watching, it comes back to the English language (no voiceover). And again I have to do as in the manual. it's bloody tiring. I heard that it is possible to set the sound to be Polish.
Please tell me how to do it step by step.
best regards

I guess? you won't do anything about it. Similarly, I have in samsung nothing helped. One of the older ones is walking and the other newer I have to switch the sound. At the same station it is good once, and if you have a movie you have to switch. Not everyone.
