>> which enables "full" audio
acceleration when ALSA doesn't have mmap. Before then, a device without mmap
automatically fell back to "Emulation" for audio acceleration.

Unfortunately it seem that none of wine developer have a sound card which
support hardware acceleartion (e.g. Sound Blaster ! Live, ...

Standard Hardware acceleration : enable secondary buffer but disable any vendor
specific acceleration such as EAX

alsa driver support mmap is not any hardware acceleration , hardware
acceleration is the secondary hardware buffer 

i.e. the sound card have to support 16 voices and hardware volume control for
each voice
