I think the problem lies with the replacement files, because even the old music is silent. But when I remove the files, the music plays again.
Look I had this problem and it was because I could not figure out how to use the re-packing steps. Basically I got up to the part to where I needed to reassemble everything and the guide gets sorta confusing I'm guessing if you are not fairly familiar with modding. HOWEVER, I have a way to get it to work WITHOUT having to repack anything. If you want to know how, this is not a joke, just e-mail me and I'll tell you. My e-mail is [email protected]
Basically it involves getting rid of the soundboot vpp in the saints row installation folder. Just cut it from there and put it somewhere safe (If you somehow made a bad "New" soundboot vpp and get rid of the original then you'll be fucked I'm guessing)
Then what you need to do is unpack the three that Packer mentions INSIDE of the installation folder. Basically it would look like this.
In the folder "C:\Program Files (x86)\THQ\Saints Row The Third\packfiles\pc\cache" you need to unpack the following vpp's into three seperate folders. (This could probably be way more efficient somehow but I have ZERO experience modding and figured this out by accident)
1. misc tables
2.sound boot
3.sounds common
So in my cache folder I have those three folders with the respective vpp's unpacked inside.
I got rid of the soundboot from the cache folder, just cut it and put it on my desktop. I took my brand new "radio_swim_media.mbnk_pc" file I created and put that in the unpacked soundboot folder, replacing the old one.
What I'm guessing happens is that since the game doesn't see a soundboot vpp anymore it just looks for the files and finds them unpacked and considers it okay. I have had zero crashes or problems doing it this way and my custom radio station plays like a champ.
Sorry if this is confusing but I don't really understand it myself lol. If you need more of an explanation e-mail me and I can try and answer your questions. Perhaps the OP can clarify on why this actually works. I'm just happy I get to listen to my favorite music while playing and could not have done it without the first 16 steps or so of the guide. Cheers.
