WASAPI is Microsoft’s own ASIO, it talks straight to the soundcard if set to exclusive mode.
In shared mode it still uses the windows audio engine.
WASAPI in exclusive mode allows you to play all audio at its native sample rate (if your audio device supports this rate).
In exclusive mode it bypasses the Windows audio engine entirely, no mixing and no resampling will take place.
As a consequence, only 1 and only 1 audio stream is playing.
Another consequence is that what the media player is sending to the soundcard must exactly match the capabilities of the sound card.
So sending 176 or 192 to a DAC supporting 96 max will fail.
If you want to play them at their native sample rate you need a DAC able to play at this rate.
DS uses the windows audio engine.
All streams are mixed/resampled to the rate as set in the advanced tab of the sound panel
