With Vista a new audio architecture was introduced.
The default (Direct Sound) sends all audio to the mixer.
In the audio panel you specify sample rate and bit depth.
All audio not having this sample rate is resampled to match this setting.
If your audio collection is mixed, you won’t have automatic sample rate switching with DS.
By design the mixer converts all input to 32 bit float and in the end of course back to the bit depth 16 or 24 the audio device is capable off. The result is dithered even when playing 1 single stream.
ASIO or WASAPI (exclusive) bypasses the mixer; they talk straight to the sound card.
It is up to the developer of the media player to match the properties of the audio with the properties of the sound card. In principle this allows for automatic sample rate switching.
ASIO will only work if your audio device supports it (proprietary protocol)
WASAPI is integral part of Vista/Win7
KS might work but this depends on the hardware.
