Q: Can you extend the boost pack audio for use with mods like Jetpack Overhaul or Better Boostpack Flight?

A: Right now I can only replace existing audio files. I won't be able to add new ones into the game without Creation Kit, I assume, and there is no existing sustained sound for PC boost packs. I could probably just make the sounds longer, but it would sound really awful if you boost rapidly.

Q: Can you change the volume for one of the sound profiles?

A: No. It seems like there's some sort of internal equalizer that adjusts audio volume. The sounds I've used are very loud, but it doesn't make a difference once they're in-game.
