Legends of Eisenwald crashes on startup

[WinterSnowfall]

The following error is shown on game startup, followed by a crash:

Here are the logs I've captured: Eisenwald.log

The game is a bit odd, in the sense that it has a launcher which also initializes dsound. I suspect the launcher is the one the main game process is complaining about (and which keeps the resources "in use"), however this behavior seems to work fine on native dsound.

Come to think of it, I believe the logs I've collected are from the launcher, not the game process, however the launcher is the one seemingly doing all the outputs.

I've investigated a bit and it seems it's not hitting any validations in DuplicateSoundBuffer, and returns a pointer in *duplicate correctly. Probably some subsequent operation the game tries to perform on that resource is the culprit, so the error message is a bit misleading.
