I took a quick looks, it does seem like some of the audio sounds aren't playing correctly. It could possibly do to an update to the game messing with the bit rate or something else. I might be able to fix it or i may have to remove it until i can find a fix for it.

Is there an issue in game with the mod? Because i do know that sometimes when NMRIH updates it breaks some things. But i can take a quick look.

Can u double check scripts and folder with sounds?

Ive spotted some errors in the voice set

the audio files i used we're like that by default. Some of the audio files we're ripped from the sound file and i think other's we're likely recorded in game (hence the lower quality). The file pack i used wasn't the best but it was also the only one available. So there isn't much i can do about that.

I was thinking of making another version later on but using Kyle Crane voice lines since Roger Craig Smith did the voice work for that. Or at least make it like a Kyle Crane/Chris Redfield voice pack that can go together.

For some reason they sound very low quality on my end, so maybe bumping up to HD can go a long way in my book to be honest with you.
