Why are Blue Ray's sound all over the place?

[El Supremo]

3. I really appreciate your comments.

But I haven't found the right settings. I have a Samsung 4K TV, a Samsung sound bar connected through Bluetooth and a Sony Blueray player. All have their own settings. I could not find "DRC" on any of them. There is a PCM vs. Bitstream setting on the TV. I like the PCM with surround sound the best. The non-surround sound setting helps a lot but the overall sound is not as good.

I think the problem is that when loud scenes occur (like crashes, explosions or rocket launches) the movie studios like to turn up the volume. This only happens with more recent films. It is the same thing that you hear in theaters. But why doesn't it happen on recent TV broadcast movies?

The latest film I watched was 'Vice'. It wasn't as bad as 'First Man' but the battle scenes were too loud.

And there is another problem too. I often cannot understand what the actors in newer movies are saying. They seem to be mumbling. I don't know if this is due to lack of enunciation or the volume. I have sometimes had to turn on closed caption to read what they say. And again this is not a problem with old movies.
