This is probably the sound settings on your TV. Turn off Clear Voice or the equivalent, disable Smart Surround, which ignores 2.0 streams and badly downmuxes 5.1 streams, and finally, check your speaker config on the TV - they’re often set to Showroom by default, which kills voice but boosts music and sfx, and there should also be options for wall proximity, which do matter, and will make the sound a muddy mess if set incorrectly.
