--- Comment #4 from Michael Stefaniuc mstefani@winehq.org --- The standard DMusic debug list should do: WINEDEBUG=+seh,+dsound,+dsound3d,+dswave,+dmband,+dmcompos,+dmdump,+dmfile,+dmfileraw,+dmime,+dmloader,+dmobj,+dmscript,+dmstyle,+dmsynth,+dmusic
If that gets too big you can try dropping "+dmfileraw"
