I have a ps3 steam upgrade in my engine. Everything works OK, except the chuffing sound is in groups of 3 like chuff 23 chuff 23 chuff 23 instead of chuff 234 chuff 234. I have the chuff rate set to 4. I tried a different sound file, but the same thing is happening. At one time it just started to work propery with chuff 234 for a while then reverted back to the chuff 23. Other MTH engines I have are chuffing in the chuff 234 sequence. The scale speed is working properly. All the other sounds are working properly.
Does anyone have an idea what might be causing this?
