Gangstar Vegas *.mpck, *.vxn & *.lwav Files

[Anexenaumoon]

Hello all!(New here) I've managed to extract these types from the sounds.g4 mobile dumped file. Now, I was wondering, how do you open these files? I'm pretty positive that these are sound files, but I have found nothing on how to open them. Being able to figure this out would help very much. I've dropped a few of these file samples below. Thank You!

.lwav it's a riff wave ms-adpcm (rename to .wav and you can play it)
.vxn looks a raw ms-adpcm
.mpck looks a variant of MP3

Tried the lwav rename, won't open. Must be compressed somehow, and an mpck is a variant as well
EDIT: lwav's work!! One file type down, two to go!

.mpck can be played back by FFmpeg
