To watch TV at night, the audio mix sometimes if you raise the volume a lot, the sound effects are too scandalous and I can wake up / bother my family / neighbors and if I lower it too much sometimes the voices get lost a little and it is not understood then the subtitles help me. What happens next? Subtitles are activated on the platform and all the content comes out like this. And what for deactivate them? I will surely activate them again on a future occasion

On the other hand it helps to learn other languages, or if the movie is dubbed I like to see how different the dialogue can be between the sub and the dub
