I agree with this. DTG "test" the content they release and these sound issues could've been avoided pre release. Then it begs the question of was this product was tested in the first place. I mean all they had to do was transfer the sound from tsw2020 and tsw2 and test to see if it was working. Instead they "release it as it is" and now they had to get a new audio engineer and train him to fix the preserved collection trains which has taken a couple of months. This would've all been prevented if they would have properly tested these sound issues and fixed them pre release. Yes DTG are a small company but this could've all been avoidable in the first place as CK95 has said. Also the reason why the M3/M7 are getting audio issues fixed first is because they have had the most noise not just here on the forums, but I assume in the technical reports, kayako and discord because Sam says that some bug fixes get high priority over others depending on how many times (or the amount of noise) a particular issue gets. Also when you have a train that has it's sound cut out like the M7 which can be unplayable to some, it's gonna lead to alot of complaints. I've seen many complaints about the issue of the M7 and some have said it's unplayable for them. "Unplayable" is a very subjective word and is interpreted differently by some players. I think if these preserved collection trains had the same level of sound quality as in tsw2020, nobody would be complaining.
