Yeah, I’ve written this under my known issue in the mod description page.
- When you have a matching ICAO code livery with the livetraffic, the livery loaded correctly, but sometimes the engine sound is missing from the live traffic. This is usually caused by a broken Sound reference from your livery for the traffic. This can be solved by adding the soundai folder from the official Asobo A320 folder and bring it to the livery’s folder, and point the aircraft.cfg to reference the soundai folder.
This is what my livery structure looks like for all my liveries.
Notice I also have the SOUNDAI folder in there? I had this copied from the same SOUNDAI folder from the Asobo A320. I place it in the livery folder. And Open the Aircraft.cfg file, and reference this in the AI FLTSIM entry.
[FLTSIM.1]
title = "Airbus A320 Neo British Airways AI" ; Variation name
model = "BRITISHAI" ; model folder
panel = "" ; panel folder
sound = "SOUNDAI" ; sound folder
texture = "BRITISH" ; texture folder
This will fix your sound issue.
