Ady teasing the probe droid score was what made me want an alternate Audio track...
It's Black or White when it comes to either re-scoring or altering audio and I appreciate people have differing views on this and may scream about an audio change and accept a visual change more readily.
The Audio changes in the first post change list are a "given" or almost mandatory decisions that I personally wholeheartedly agree with and I can only imagine that there is someone out there that would argue that the new special edition Boba Fett voice sounds better or the "bring my shuttle line" is inferior to the new one..
So those are not really an issue but when the probe droid score came on with the new scene... It worked so well that I now struggle to see that without the music. Although I am not sure on the fleet grouping should be as in the original film or the new version this I am a bit torn on.
Probe Droid score = 100% for it
fleet grouping = 50/50 (when sound effects are added for the ties and Vader breathing this could actually sound fully amazing and be 100% for it)
But this adds weight to an alternative audio track for the very reason that some will simply reject an audio change while others will embrace them and more so than visuals which is a bit strange as most of our perception is visual.
Certainly an interesting subject for research on perception.
aside from this I just pulled a list off wiki of audio changes from theatrical vs special edition weather or not this is totally accurate I do not know the answer but likely not as C3PO saying "I don't want to die" without the cut off is not listed neither is the Gantry and reverb on voices or wind sound effects during sabre duel.
as for some of the original sound it's been so long I honestly can't remember the original sound of "the first transport is away" or the original "who are you" when C3P0 get's shot for instance this has gone from memory. Neither did I realize there was so many audio changes

There were also a large number of audio changes to the Special Edition version, all of which were incorporated into all subsequent releases of the film, unless otherwise noted.
- On Hoth, right after C-3PO tells R2-D2 to "Switch off", R2 gives out a little "blurp".
- When Luke collapses in the snow, he lets out a grunt as he lands on his face.
- Han says, "until I can get the shelter up" instead of, "until I can get the shelter built."
- Luke says an additional "Ben... Dagobah..." just before Han says, "I thought they smelled bad on the outside."
- When C-3PO tells Luke, "It's so good to see you fully functional again", Luke replies, "Thanks, 3PO."
- The line "Headquarters personnel report to Command Center" is said three times instead of two.
- The line "The first transport is away!" is said in a different voice.
- When R2-D2 is being loaded into Luke's X-Wing, C-3PO says "and" before saying "do take good care of yourself."
- Han's line "Transport, this is Solo. Better take off, I can't get to you. I'll get her out on the Falcon" is followed by, "Come on."
- In the asteroid field, after C-3PO says, "Oh, this is suicide", he says, "There's nowhere to go."
- In the scene where R2-D2 is spat out by the bog beast, Luke says "You were lucky to get out of there," instead of "You're lucky you don't taste very good." This line was not in the 1993/1995 THX mix.
- Yoda makes a frightened "AAHHH" sound when Luke points his blaster at him.
- Yoda says, "Yes, run!" before "Yes. A Jedi's strength flows from the force." The following lines, "But beware the dark side. Anger, fear, agression. The dark side of the force are they. Easily they flow, quick to join you in a fight" are also much louder and clearer.
- The Imperial fleet establishing shot after the magic tree scene has a different TIE fighter sound effect.
- A different part of The Imperial March plays during the shot of the Imperial fleet right before Darth Vader kills Captain Needa.
- In Cloud City, after C-3PO says, "That sound like an R2 unit in there. I wonder if it..." he says "Hello?" only once instead of twice.
- Before C-3PO gets shot, a different voice says "Who are you?"
- While C-3PO is on Chewbacca's back when they enter the carbon freezing chamber, the line "Now remember Chewbacca, you have a responsibility to me, so don't do anything foolish" is heard louder and clearer.
- During the duel, when Luke knocks Darth Vader off the platform, Vader lets out an "ooooh!" instead of an "aaargh!"
- Lando Calrissian says "Attention" twice (instead of once) when he speaks on the Cloud City public address system.
- Lando's line at the end, "Luke, we're ready for takeoff." is a different take.
- In the final scene, there is no tracked music from "Yoda and the Force"
- "The Imperial March" is partially repeated in the ending credits music to make room for the Special Edition release credits.
