I’ll check this out for you and if needs be the dev can try and push out an update if there is a better alternative.
I believe this is because they were combined together and one or the other will play automatically depending on aircraft type.
What method(s) have you used when trying to contact “us”? In my personal experience the customer service is outstanding. Remember that the best way to get in touch is via the community here.
Yes, however it sometimes is hard to find them. Your welcome to make a #features request if you are able to find the audio for it or if you DM me with a couple of airline i’ll point you in the right direction.
As i previously said its hard sometimes to find sound packs for different aircraft other than the one on here (which is not always the 737) but if you find it then i’m sure the dev will be able to implement it with it autoselecting the one relating to the aircraft you fly.
I hope this helps and if you have any more issues please do not hesitiate to make another support topic.
