AFAIK Railwaves (who primarily did sound packs for MSTS) are long defunct so any fixing up of their products will need to be done by the user, to get them working in TRS2019. Their biggest contribution to Trainz was a version of the West Somerset Railway, IIRC.
Railwaves have never done anything for the DTG sim and surprised this came up, the OP fairly obviously referring to TRS2019. Not his fault if N3V and DTG can't agree between themselves to name their products slightly differently to avoid consumer confusion...
