AT this current time, the mod is broken. I did exactly what you said and nothing worked, I tried putting the unzipped sirenmod into the siren mod folder, nothing. I did not want to edit anything though, im no expert in this stuff. But yeah anyway this is broken, just a heads up before you try to install.
The mod work fine, you did a bad install or you have the wrong version. You have both sirenmod.zip and sirenmod folder in your mod folder ?
i think the .13 update now has dirt sounds of its own, base on some videos i watch about the early access of the new update, as well as i believe understeer sounds
I am updating the mod --- Post updated --- Mod updated ! -Big improvement to scratch sound. The sounds are now in 3D -The alarm sound now use the app to toggle instead of the old way. The app buttons of the brake squeal and alarm are showing the value of the latest car you drove. I'll fix that bug later If you need help with the car alarm / brake squeal, check the How to use section of the post. -Fixed the mod for 0.13 update -Removed custom crash sounds -Removed dirt sound when driving on dirt -Removed custom tire sound (even if it was disabled by default) -Removed tire deflate when drifting too much (even if it was disabled by default) I didn't tested the mod very well so it may have some bugs ! Please report me if you find any bug.
That mean I need to disable the default sound of the game, then add the mine make it work with the new update that would take some time. But I can yes
Made it quickly, don't forget to enable it in settings file, it's disabled by default. I'll add it back in the next update
