[ros-diffs] [janderwald] 44721: [WDMAUD.DRV] - Move the routines which interact wdmaud.sys to legacy.c - Implement opening / closing of audio pins as well as writing / reading audio bytes from / to it - By defining USE_MMIXER_LIB, wdmaud.drv bypasses wdmaud+sysaudio and directly writes/reads the audio bytes to portcls.
