Titanfall Audio Installation Failed! Decode: Corrupt secondary header 1.

Everyone who has had this problem too.

I was instructed by Origin live chat support to run  repair on Titanfall so the game files could be reverified. Hopefully this is the fix if not I will be contacting them again. I will let everyone know though if it works when it's finished. Currently it's attempting repairs after verifying the game files. I'm sure in the next few days this problem will affect a great deal more then the 7 of us.

Okay that didn't work! 

Instead it is now a new message:

Titanfall Audio Installation Failed!

Decode:Corrupt or missing data in bitstream. In file "\\?\C:\Program Files (x86)\Electronic Arts\Titanfall\vpk\Client_mp_common.bsp.pak000_004.vpk" Offset 1874154794, size 61952. 

So I really have no idea what the hell to do tomorrow I'm calling support maybe they will have a new answer that actually works.

I talked to support and they said they couldn't help me with the problem. Ugh

Luckily the woman I spoke with earlier was very eager to help but I couldn't do anything else while talking to her becaue I was attempting to repair the game. She also sent me an email though with some other methods of trying to fix the issue here it is if anyone wants to give one a try and let everyone know if it works.

Ok I just tried @grimwake solution  and it seem to work. I didn't take any chance and deleted all the .vpk name in the list. 

Then I installed the game again and it work perfectly. 

Afterward I did the repair and this time around it didn't give me any error and the game is now installed on Origin. 

But of course there's no way for sure that it's working perfectly since I can't launch the game, but it's the only solution thus far that have worked. 

Thanks !!

Be aware that the servers will be up and back down again right up to the official start date.  You should have some pre-release opportunities for testing. 

Good to know, I just bookmarked it. Since right now it's installed I don't want to try something else but if on launch day it doesn't work I will certainly try this. At least, it's good to know there's working solution out there. 

Grimwake, 

Thanks for the help your solution worked. 

Thanks for the help Grim it worked.
