Were the original unaltered mono or 2.0/4.0 matrixed sound tracks for the original trilogy on a home release?

From my understanding(please do correct me if I’m wrong) each of them had a mono track(16mm film?), a 2.0/4.0 surround matrixed track(35mm film), and a 6 channel 4.2 surround track(70mm film). And on the 4.x tracks the rear channel surround was split/run into two rear speakers to give the surround more well surrounding. Like i said if im mistaken please correct that.

Now obviously the 6 channel 4.2 track couldnt be on any release until dolby digital audio became a thing on laser discs(even then the .2 would have to both be sent to DD’s .1) and by then lucas was hard a working on the SE release. But were the un altered mono, or matrix 2.0/4.0 on any? I know even in 93 with the definitive edition laser discs I have those were remastered with a mix of the matrixed and 70mm’s 6 channel. Which for all I know could be better than the non 6 channel theatrical tracks but i haven’t been able to know yet. Also dont know anything about releases prior to that 😕

So yeah sorry for rambling… basically were ether of the mono tracks or the matrixed 2.0/4.0 tracks from the GUOT ever released?

Yes, the first LD releases had the theatrical Dolby Surround mixes (the 2.0/matrixed 4.0). These tracks are included on Despecialized and 4K77/4K83’s releases, too (and 4K83, as a bonus, has the actual Dolby Surround audio from the print as the primary audio track).

The mono tracks weren’t, though - the 1977 35mm mono we have from early TV broadcast recordings, and the ESB and ROTJ 16mm mono tracks we have from 16mm prints.

There is a poster on the binaries that has posted all of the Star Wars laserDisc audio rips in lossless - I believe it is every audio track from every LD release.

I have it bookmarked at home to use for my “Faces” project.

My understanding is that all the home video releases had the matrixed surround in the stereo tracks. The 1985 mix was done differently for CBS Fox. Rather then use the studio mixed stereo track, they used the 4 indivdual tracks and encoded them in house to matrixed surround. I don’t know who did the mix for the Definitive Collection/Faces/2006 GOUT, but it definitely is matrixed surround. I have decoded all of them and certain scenes reveal improved sound on a 5.1 system, particularly the Luke and Leia chasm scene and sound like the distinct channel audio of the 97 SE and later.
