sound.cache colliding

[Mery]

Well, I tried to add some custom music to my L4D, so I created .vpk with sounds. Few of them didn't work at all, so I generated a seperate sound.cache for them. But then in "Add-Ons", game tells me that I have to check in console for colliding files, and I see something like this:

File sound/sound.cache collides in VPKs:
Some Dubstep/Nintendo games sound replacements
Old Spice charger sounds

What to do?

The conflict detector checks for similarities in file names between mods, as I understand. Sometimes these files will actually conflict, but unless they replace the same file, they probably won't. Try a play-test, and if the sounds work, ignore the conflict.

Well, still works. But that leads to another problem.
Even cached, some sounds still refuse to play. I mean, for example, stepping-into-spitter-goo music plays properly, but everything else from the mod (like credits music) refuses to do it at all (stock music plays)

Are the sound mods the proper format? Such as file structure, frequency, channel number, .wav type, audio length?

[Mery]

They're all the same as the original files, when we're talking about format and stuff

Strange. I'm new to sound modding myself, so I can't help any further at this point. Hopefully someone else can shed light on your problems.
