DIY Sound Fix for Silent Mod Cars.

Firstly hold auditions. Find the Kunos car that gives you the sound you want for the silent mod. In the following example I have used the Lotus 49 as the sound donor (all cars should sound like that anyway ::)

This may seem a bit complicated, but it really isn't. Anyway, the worst that can happen is you end up with no sound on the Mod Car, so you're no worse off.

In Windows Explorer locate the file called GUIDs.txt in
C:\ProgramFiles(x86)\Steam\steamapps\common\assettocorsa\content\sfx
Copy it and paste it somewhere safe, somewhere you will be able to find it after, like My Documents.
Open the version you just copied in Notepad. Every line that contains the name of a car that is NOT your chosen donor car must be deleted.

You should end up with a file like this (except it will show the name of your chosen donor car rather than lotus_49)::

Whilst still in Notepad use Edit, Replace
In Find what enter the name of the mod car you are fixing exactly as it appears in the lines you have left in the GUIDs file. For example lotus_49.
In the Replace with box enter the name of the mod you want to fix in exactly the format used in it's cars content\cars\ folder name. For example lamborghini_miura_sv
Now click Replace All

Save the Notepad file as GUIDs.txt in the sfx folder of the mod car you are fixing. For example:
C:\ProgramFiles(x86)\Steam\steamapps\common\assettocorsa\content\cars\lamborghini_miura_sv\sfx\GUIDs.txt and overwrite the existing one.

OK, almost there...

Go to the sfx folder of your chosen donor car in WIndows Explorer. In my example it would be:
C:\ProgramFiles(x86)\Steam\steamapps\common\assettocorsa\content\cars\lotus_49\sfx\
Locate the file with the .bank extension , in my case lotus_49.bank
Copy the file.
Go to the sfx folder of the mod car you are fixing. In my example it would be:
C:\ProgramFiles(x86)\Steam\steamapps\common\assettocorsa\content\cars\lamborghini_miura_sv\sfx\
Now paste the file you have just copied into that folder.
You will notice that there is already another file in that folder with the .bank extension. In my example it would be lamborghini_miura_sv.bank That's the old one that no longer works and needs replacing.
Delete this file.
Now rename the new .bank file you just pasted in there to match the file you just deleted. In my example it would be from lotus_49.bank to lamborghini_miura_sv.bank

Et voilà!

You should be aware that underscores and lowercase letters are extremely relevant and should not be missed out or substituted.

PS: 10 minutes after I posted this I realised I had made a bit of a muckin' fuddle of it, but I was on the way to the dentist by then. Now it's fine... unlike my mouth.

I downloaded the Dodge Daytona Charger and it had no engine sound, I found this post but did it slightly differently. I also have the Dodge Charger RT Magnum, I swapped the sound.bank file from it and changed the name like above. Then I got the Magnums guids.txt file from the same folder as the sound.bank file (not the one from the common SFX folder) and opened it in notepad like above, and did the replace thing changing all the references from the Magnum to the Daytona Charger like above.
Tried it and it worked a treat, thanks to Rufus Bagsby's post it showed me what was necessary.

Forgive me please but this fix is useless. Better way is extract bank file and fix original sound for car.

How do you do that?

And not being rude it was the only way I could find to fix it. The GUID's file was one someone copied from the main SFX directory and was 72kb's so it was screwed up also.

Or you can just use Content Manager and do this same thing with just a few clicks in about five seconds. Go to Content, click on the car that needs fixing, click Update Sound, click on the car whose sound you want to use, done. :thumbsup:

This is useless solution if you have original engine sound.
The OP is about replacing mod car sounds with Kunos car sounds. That's what Content Manager does but with only a few clicks and no copy/paste or editing of files.

Interesting. I kind of assumed the GUIDs for original cars where built into the car somehow, and never knew they just were elsewhere.

Content Manager isn't an option because I really like the original theme. So this is certainly worth a good try.

Well, it's not a fix, it's a workaround. There is no fix. You just cannot "fix" the original sounds without updating them in FMOD, period.

Just use Content Manager to swap sounds then exit and run AC as normal.

Semantics. It 'fixes' the fact that some mod vehicles have no sound at all. ;)

The car I swapped the bank and guid files from has the same or very similar engine, to the Charger so I think it's pretty close to how it should sound.
