--- Comment #4 from Michael Stefaniuc mstefani@winehq.org --- Actually the leak from comment #3 is in the initialization of winmm.dll which gets de-initialized on dll unload. As the initialization happens only once the "leak" is not a problem and thus can be safely ignored.
Also the rest of the entries are "possibly lost" and all but one have the same pattern: test_InitAudio (performance.c:97) DMUSIC_CreateDirectMusicImpl (dmusic.c:518) midiOutGetNumDevs (winmm.c:291) (lolvldrv.c:508) MMDRV_Init (lolvldrv.c:508)
MMDRV_Init() leaks are probably a good candidate for a generic suppression.
For the remaining "possibly lost" I have submitted the patch: https://source.winehq.org/patches/data/176406
