99% of the time, the cause is trying to output a 5.1 signal into a Stereo setup (Like your TV speakers). A 5.1 signal is 5 speakers and 1 subwoofer. The speakers are front left and right, rear left and right and - the important bit - the centre channel. The centre channel tends to be where all of the dialogue comes from, while everything else comes from the other speakers. But what happens if you don’t have 5 speakers? What if you only have 2? You can’t ignore that audio so you’ve got to mush it together somehow and now you’ve got dialogue and explosions coming out of the same speakers with mixed results.
It’s not about not having a professional setup mixed the same as a theatre, it’s usually about a setting somewhere that’s incorrect. If you’re only using your TV’s speakers, there’s a good chance something somewhere is trying to give it a surround sound signal and it’s trying to downmix that to stereo. Usually you can fix it by adjusting a setting somewhere, either the TV itself or whatever app/box is sending the TV the signal as most sources do actually come with a stereo mix.
However, a better way of solving it is getting yourself a soundbar. It doesn’t have to be an expensive one at all, even the cheaper soundbars will sound better than your TV ever will and they’ll at least have a 3.1 signal that’ll separate out the sound effects/music from the dialogue because usually that dialogue goes through the centre channel which you now have. You can also usually adjust the volume of that channel independently.
Note that nobody would suggest that a cheap soundbar is anything close to a “professional setup”. Most audio folk would turn their nose up at the idea of using a soundbar over a full surround system but you know what, they’re pretty “good enough” for most folk and if you care about media consumption, it’s a nice improvement.
