This is what i get / SAMv2.TC1.14 Log -
I: Ƞ.MaxVolume.RawValue * ē / 100.0f = 0
I: Ƞ.CurrentVolume.RawValue = 0

According to the developer of SAM v2 TechCoder the issue is that mod is not working according to the established standards (and therefore not reporting back through the API....) This is what the script follows - you should make sure mod does this (talk to the dev of the mod - if they don't follow the rules {and, sadly, that is often the case..}, nothing I can do)
