        to Pa_OpenStream() if flags contains the paWinDirectSoundUseLowLevelLatencyParameters
        flag.

        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
