PS4 Dear Developers... When Will You Decide To Fix The Audio Of Old Maps Converted To Tsw3?

I read hundreds of threads and posts from people complaining that the sound of the engines is almost or completely muffled on TSW3. Old maps converted to TSW3 where the graphic level clearly increased while the audio didn't take care of it.
Where in a simulator audio effects are fundamental, on various maps that I played on the old Train Sim World 2020, try on Train Sim World 3 some sounds don't even exist anymore or are so muffled that you can't hear them.
I don't understand how people can keep releasing new maps without even fixing the old ones!!
I hope something is done, if it is not possible to correct the audio conversions of the train sounds, at least see if the volume of the same is further increased from the main menu.
Yesterday evening I opened and gaming some old maps on TSW2020 and there is no comparison for the high audio quality of the diesel train where compared to TSW3 it is quite painful!
I'm hoping for a fix but, I just see new maps being made, not giving a damn about what's been before

 

I have submitted a ticket. They just replied, saying things like "thanks for your report...." "stay tuned for future game updates".. from the series "we give a LOVE"
I thought it was more of a tease, a "copy and paste" answer. Evidently they don't give a damn about improving the audio.. just making new maps to make money..

Eventually I decided to play the maps for each type of TSW series they were made in;
I have the collection edition of Train Sim World 2020 and there are 5 maps included, the audio is incomparable to the same map played on TSW 2 or 3. The graphics certainly are better on TSW2 and TSW3 but the audio is shameful!

I don't understand how they could have overlooked such an important element or even worse how they failed to notice it. Yet it would take very little to change the audio settings from the main menu in TSW 3 in order to balance the sounds in general... instead of having everything at 100% which doesn't really make sense, set some values to 50% and then everyone goes down and raise what he wants.
This would also solve the problem of the low sounds of the locomotives, I don't understand why instead they don't deal with it at all but only churn out new maps to sell
