- Set the audio pin to KSSTATE_RUN if it is wave-out pin - Implement support for manually starting / stopping a pin, which is used for recording [WINMM] - Add a hack for handling requests with WAVE_MAPPER [PORTCLS] - Pass correct flags to KsProbeStreamIrp when the irp has not already been probed (DirectKs) [WDMAUD] - Set correct irp dispatch code [SYSAUDIO] - Remove a hack [MMEBUDDY] - Return no error for MXDM_INIT message - Add support for completing multiple wave headers at once - Use new functions to implement WIDM_START / WIDM_STOP - ReactOS now "supports" wave in recording. Tested with Audacity / sndrec32 @ XP, WIP svn path=/trunk/; revision=43765
