The sound problems can be fixed by going back to the original 2-channel Dolby Stereo mixes for 1-3. They were last found on the first Studio Canal European Blu remasters from nearly a decade ago I believe.

Whenever the 5.1 soundtrack was produced (I think for that release), it screwed up much of the stereophonic fidelity of the source audio, most especially 2. There are a number of scenes in 2 where there should be discrete sound effects coming out of the rears, left and right hand sides, which you can hear in the original 2-channel mix (which remember is still full Dolby Surround when properly matrixed, as intended). But when the 5.1 track was produced, it folded much of those effects down into the center instead. It's a shame. The music also sounds "cramped" in comparison to the original mix.

The overall "imaging" on the 5.1 tracks is poor -- and it didn't need to be. The original Dolby Stereo tracks have a nice soundstage for the music and effects, and could've been just fine "as is" had they only included them. Sadly on the 4K UHD's they just re-used this same crappy 5.1 track, leaving off the original 2.0 Dolby mixes.

As much as I like the UHD transfers the audio is a major problem for me. I ended up tracking down those Blu-Rays that have the original audio again (I had sold them off) because the 5.1 tracks are a real detriment to the overall presentation of those films.
