[PATCH 02/10] dsound: Request that WinMM perform audio conversion if the hardware doesn't support the requested format

Prior to this patch, dsound will fail if the user requests a format that
the hardware does not directly support. According to the tests,
IDirectSoundBuffer::SetFormat() should always succeed, even if a format
isn't directly supported. So, we should specify the WAVE_MAPPED flag to
wave{Out,In}Open in order to request that WinMM convert the audio for us
if the hardware doesn't directly support it.
