to be precise:
msacm.drv is the wave mapper (it both allows to choose from several physical
output device, as well as inserting filtering and conversion algorithms
between an audio stream provided by an application, and the audio stream
the hardware is able to render
msacm.drv uses the DLL pair msacm/msacm32 to provide the loading/unloading
an invocation of those filters and conversions (which are external DLLs)
there are three layers to look at:
mmsystem/winmm
msacm.drv
msacm/msacm32
native mmsystem/winmm requires native msacm.drv (for 16/32 issues)
native msacm.drv is 16 bit, so relies on msacm. builin msacm is not as well
implemented as builtin msacm32
I don't remember all the details, but IIRC, I couldn't get native msacm/msacm32
to run because of registry settings I never bothered to look into
currently, the only working solution is
mmsystem/winmm/msacm.drv/msacm/msacm32 all builtin
however, mmsystem/winmm/msacm.drv builtin and msacm/msacm32 native should be made
working as well as
mmsystem/winmm builtin and msacm.drv/msacm/msacm32 native
A+
