Can an Integrated Audio Chipset Pass Bit Perfect Audio?

In general, WASAPI operates in two modes. In "shared" mode, audio streams are rendered by the application and mixed by the global audio engine before they're rendered out the audio device. In "exclusive" mode, audio streams are rendered directly to the audio adapter, and no other application's audio will play. Obviously the vast majority of applications will operate in shared mode, that's the default for the wave APIs and DSound. One relatively common scenario that WILL use exclusive mode is rendering content that requires a codec that's present in the hardware that Windows doesn't understand. A simple example of this is compressed AC3 audio rendered over a SPDIF connection - if you attempt to render this content, if Windows doesn't have a decoder for this content, then DSound will automatically initialize WASAPI in exclusive mode and will render the content directly to the hardware.
