I believe the fix went like this:
open assets folder
open sounds folder
sounds.txt file, right click, turn off read only, apply.
open sounds.txt, there are a number of esg files, the ones that are important are the loop files
eg: wave kSndESG0Loop esgloo0.wav ESG Level 0 Sphere Loop
you want to put [rem] at the start of the line
eg: [rem]wave kSndESG0Loop esgloo0.wav ESG Level 0 Sphere Loop
Do that for each esgloop line (4 total) and that should stop the eternal esg noise.
Save the file, put it back to read only and you are good to go.
