So i was playing with the horn on the AC4400CW and using it in conjunction with the Doppler Effect when it stuck on but after that it the sound went away from me and the horn didnt work anymore on the loco later on it came back and went away and came back it was weird
One of the issues with TS is that the number of sound channels is limited and you can get anomalies in sound when the application runs out of channels in the sound mix. I believe Searchlight Simulations mentions it somewhere, maybe in the manual or one of their u-tube tutorials - basically out of their control.
