[ros-diffs] [janderwald] 44326: [WDMAUD.DRV] - Implement support for resetting a stream (not yet used) - Don't translate the error again in QueryMixerInfo as SyncOverlappedDeviceIoControl has already translated the error - Don't touch the cbSize member when opening a wave device, as the caller might have passed a WAVEFORMAT struct instead a WAVEFORMATEX struct. Fixes winmm_winetest wave / mixer crashs - Query all available events when an mixer event is fired

[WDMAUD.DRV]
- Implement support for resetting a stream (not yet used)
- Don't translate the error again in QueryMixerInfo as SyncOverlappedDeviceIoControl
has already translated the error
- Don't touch the cbSize member when opening a wave device, as the caller might have
passed a WAVEFORMAT struct instead a WAVEFORMATEX struct. Fixes winmm_winetest wave /
mixer crashs
- Query all available events when an mixer event is fired
