> Standard - Uses hardware voices for the primary and secondary buffers, no

> Full - Uses hardware voices for the primary and secondary buffers, uses

AFAIK , "Test sound" in dxdiag only play using software buffer with different
rate and format in wine, still cannot play using hardware buffer in wine since
dwFreeHwMixingStreamingBuffer is zero
