Well, I've been trying to set this up for a long time now, and iI haven't been able to achieve it.

I got all four files:
zones/radverb/default_alv.radverb.csv
zones/snapshot/default_alv.snapshot.csv
zones/default_alv.all.csv
zones/default_alv.english.csv

All of them, set up using these https://pastebin.com/DFe6Jwab

And right now i got this :

But the weapon sounds don't work...

Weaponfile notetracks:
sndnt#fly_1911_mag_out
sndnt#fly_1911_futz
sndnt#fly_1911_mag_in
sndnt#fly_1911_slide_forward
sndnt#fly_1911_slide_back

Launcher error(tutorials say that it doesn't affect the mod):
Notetrack-to-Sound: Weapon 't7_m1911_zm' has bad entry; notetrack 'sndnt#fly_1911_slide_back' doesn't have a corresponding sound.
ERROR: aliases failed to load

Please help.

You need to put the file path here too, in the end of the soundalias line, in "file_pc"

oh, thanks, it worked
