TODO ** NOT IMPLEMENTED **
These settings control the number and size of host buffers in order
to set latency. They will be used instead of the generic parameters
to Pa_OpenStream() if flags contains the paWinDirectSoundUseLowLevelLatencyParameters
flag.
If PaWinDirectSoundStreamInfo structures with paWinDirectSoundUseLowLevelLatencyParameters
are supplied for both input and output in a full duplex stream, then the
input and output framesPerBuffer must be the same, or the larger of the
two must be a multiple of the smaller, otherwise a
paIncompatibleHostApiSpecificStreamInfo error will be returned from
Pa_OpenStream().
