Xbox Lirr M7 Audio Issue. I Thought This Was Supposed To Be Fixed

The M7 on lirr when accelerating when in free camera will have the audio on the middle of the train cut out making the train a bit quiter and then cut back in. The front two cars of the train will have audio but the middle two won't. At times when at rear camera at the rear of the train, there will be no audio of the train coming from the rear. It's the same bug/issue that the train has had ever since it was released for tsw2. I thought the patch was supposed to fix that issue. All that had to be done was get the M7 up to TSW2020 standards. I don't get why sounds in the middle of the train would cut out because in real life that wouldn't happen nor do I get why that wasn't fixed.

The alerter on the M7 as well will at times get quiter as I go along my journey.

Post below if you had a similar issue

 

Yeah they completely destroyed this route in exchange for the PIS. ACS system is broken too now as well

 

And they still got the pis modeled wrong. I don't get why the audio wasn't fixed
