Fireworks too loud!

Is there any way to turn off the sound of fireworks? It’s really annoying when you just want to hear the engine of the car!

Interesting. The fireworks and their associated sound, even at the darkest hour of the evening, are very intermittent and, in my opinion, hardly do much to interfere with the sound of the car. Anyhow, the answer is: no, there is no way to turn off the sounds of the fireworks without turning off the audio of the ambient sound which will effectively mute your game entirely.
